Exoplanets in the view of the European Extremely Large Telescope

Frans Snik, Staff researcher, University of Leiden, Sterrewacht Leiden

We know from indirect observations that all stars have a large chance to harbor a planet that could support life. However, it still remains extremely challenging to study exoplanets directly, as they are typically millions to billions times fainter than their parents stars. We are developing optical systems (adaptive optics, wavefront sensors, coronagraphs, spectrographs, polarimeters) to not only directly observe exoplanets, but also analyze their light to find signs of life. We are applying our technology at large telescopes all over the world, and aim to build the ultimate instrument for the 39-m European Extremely Large Telescope currently under construction.

Label-free single-molecule biosensing: towards continuous monitoring of biomarkers

Peter Zijlstra, Assistant Professor, TU Eindhoven

I will describe our progress on the label-free detection of proteins using metallic nanoparticles. Such a plasmon sensor optically detects interactions of analyte with receptor-functionalized particles by monitoring wavelength shifts of the plasmonic nanoparticle. Using particle-based detection ensures high signal-to-noise ratios in a simple optical microscope. We recently reached single-molecule sensitivity, which opens up exciting applications for the continuous monitoring of biomarker concentrations in a biological environment.

New fiber interferometry sensing systems for applications in life science and remote sensing

Niek Rijnveld, CEO, Optics11 BV

Among the many optical fiber sensing techniques, fiber interferometry provides the best sensitivity, highest bandwidth and highest dynamic range. Interferometry means to directly measure the phase of light, which Optics11 is able to do with femtometer level precision.
By combining fiber interferometry with micro-manufacturing technology, Optics11 has created a range of products and measurement systems for life science and remote sensing applications. In the life sciences, the Piuma Nanoindenter series provides measurement of micro-mechanical properties of extremely soft biological samples. In remote sensing, the ZonaSens and DeltaSens measurement platform allow measurement of acoustics, accelerations, and many more parameters in challenging environments.

Ewold Verhagen FOT17
Optical isolation based on radiation pressure

Ewold Verhagen, Scientific Group Leader, Amolf

The principle of reciprocity dictates that light can always propagate in two directions. There is an active search for mechanisms that break reciprocity in miniature systems to create on-chip isolators and circulators without a strong magnetic field. A possible route relies on spatiotemporal modulation of the refractive index, which is straightforwardly achieved in optomechanical systems. We experimentally demonstrate that radiation pressure can be used to induce optical isolation in optical ring resonators, and derive the minimal requirements to create nonreciprocity in a wide class of systems that couple a pair of optical modes parametrically coupled to a mechanical mode.

In vivo optical imaging: new tools, applications and translation to the clinic

Clemens Löwik, Head Optical Molecular Imaging, Erasmus Medical Center Rotterdam

Whole body fluorescent imaging and bioluminescent imaging using gene reporters expressing fluorescent proteins or luciferases are now widely applied in small animals to study all kinds of biological and molecular processes. New developments concerning new mutated luciferases and new  (caged)-luciferin) substrates will be discussed making optical imaging even more sensitive with higher resolution. Also combination with other imaging modalities will be discussed. Finally I will also show our progress in using optical imaging for image guided surgery.

Interventional imaging with light in cardiology

Gijs van Soest, Associate Professor, Erasmus university

Intravascular imaging guidance improves outcomes in minimally invasive treatment of acute coronary syndromes. I will review recent developments in optical imaging technologies for assessing coronary atherosclerosis and stents. These include optical coherence tomography and near-infrared absorption spectroscopy, which are in general clinical use, but also more experimental ones based on photoacoustic and fluorescence imaging.

Mass Spectrometry Imaging in Clinical Research

Benjamin Balluf, Assistant Professor, Maastricht University

Mass Spectrometry Imaging is a technique that allows studying the spatial distribution of molecules on the surfaces of samples. The unlabelled character and histological specificity have made it a powerful discovery tool especially in the field of biomedical research dealing with solid, biological tissues. This lecture will give a brief overview of the highlights of clinical research performed in the last years by Mass Spectrometry Imaging in general and our laboratory.

Jeroen Kalkman FOT2017
High resolution 3D zebrafish imaging with optical projection tomography

Jeroen Kalkman, Assistant Professor, TU Delft

In 3D optical projection tomography light does not behave in the ideal way that X-rays do in X-ray computed tomography. Effects of diffraction and refraction can severely affect the image quality in optical tomography when not properly taken into account. In this presentation I will show how these effects can be mitigated by using computational image reconstructions algorithms. Results on tomographic reconstructions of zebrafish demonstrate the opportunities this offers for high resolution, high contrast, imaging of small animals.

Challenges and Chances in Integrative Microscopy

Gerhard A. Blab, Utrecht University

Both Electron- and Fluorescence Super-resolution Microscopy are well established techniques with a wide range of applications in Life  and Materials Science. I will present some results of our ongoing collaborations within the STW Microscopy Valley programme, in which we aim to combine both light and electron microscopy in a single system; while there were several challenges to overcome, we have successfully built a working prototype. Such an integrated system will afford the advantages of both imaging modalities: specificity and versatility from the fluorescence and nano-metre resolution from the electron microscope.

Erik Manders FOT17
Re-scan Confocal Microscopy

Erik Manders, Associate professor (UvA) and Scientific director (

In the last few years the Re-scan Confocal Microscope (RCM) has become a well-known technology to obtain 3D-images with an improved lateral resolution (170 nm) as compared to standard confocal microscopy (240 nm). The technology is based on a very simple modification of the standard confocal microscope; an additional scanner projects the emitted light on a sensitive camera. The highly photon-economical detection system strongly reduces the noise level in RCM images. Based on the standard RCM for multi-colour 3D-imaging, we have developed several other modalities tuned to specific biomedical application.

Nanocapillary Electrophoretic Tracking of Single Particle Charge

Sanli Faez, Assistant professor, Utrecht University

Tracking the motion of single nanoparticles is a gateway to understanding physical, chemical, and biological processes at the nanoscale. In single particle tracking one can directly visualize the intermediate steps of a reaction, which is often untraceable in bulk experiments. I present a new experimental platform that enables tracking of free, unlabeled nanoparticles and macromolecules over a wide range of time-scales. The key element of this technique is a single-mode opto-fluidic fiber, in which the high-index core contains an open nanometric channel that runs along the entire fiber axis. I report experimental detection of faint scattering and fast thermal diffusion of nanoparticles and single viruses.

An integrated Nano-Opto-Electro-Mechanical-System for on-chip spectrometry and nanometrology

Rob van der Heijden, Associate Professor, Department of Applied Physics and Institute for Photonic Integration TU Eindhoven

An integrated Nano-Opto-Electro-Mechanical-System, with a footprint in the range of 15x15 square micron, is presented that can be configured either as a high-resolution on-chip spectrometer or displacement sensor. It is based on a double membrane, mechanically tunable photonic crystal cavity. The wavelength resolution is about 0.1 nm for broadband spectroscopy or sub-pm in wavemeter mode. The displacement resolution is estimated to be some tens of fm/root(Hz). The device is intended for applications in low-cost, high-performance, on-chip sensing systems of a multitude of parameters and for nanometrology operations in the nanomanufacturing industries.

Building blocks for a future quantum internet

Wolfgang Löffler, Research Associate, Leiden University

An essential building block of a near-future quantum internet are nodes where quantum information can be coherently transferred between photons and solid-state qubits. This has to be done with high fidelity and high success probability, and should be integrated with optical fiber technology to enable complex networks. Here we show a first prototype of such a photonic quantum gate by demonstrating an all-fiber coupled solid-state source of identical single photons. It is based on a quantum dot in an integrated micro cavity for cavity-QED enhancement, we obtain state-of-the art single photon purity, indistinguishability and brightness.

Femtosecond opto-magnetism

Alexey Kimel, Professor, Radboud University

Controlling the magnetic state of media with the lowest possible dissipations of energy and simultaneously at the fastest possible time-scale is a new and great challenge in fundamental magnetism. The control of magnetism by light is one of the promising approaches to this problem, because such methods may access timescales of a picosecond or less. In my talk I will show that an ultrashort circularly polarized laser pulse acts on a magnetic system as an equally short magnetic field pulse with the strength up to few Tesla. Using such opto-magnetic pulses we have succeeded to discover novel routes for magnetization reversal and demonstrated the fastest ever and least dissipative magnetic recording.

Hybrid perovskites: from solar cells to x-ray detectors

Maria Antonietta Loi, Full Professor, University of Groningen

Organic inorganic hybrid perovskites after only few years from their first use in a photovoltaic device have imposed themselves as “the new material” for photovoltaic applications. With certified power conversion efficiencies above 22% they will soon come in competition with crystalline silicon based devices. In my lecture I will describe briefly the outstanding physical properties of hybrid perovskite, with special emphasis for their extreme defect tolerance. I will then discuss their application in photovoltaic devices and as very efficient x-ray detectors.

Nanoarchitectronics: a new paradigm for a European flagship program

Prof. Dr. Giampero Gerini, Senior Scientist - Optics department, TNO

Nanoarchitectronics is a new paradigm which aims at the development of a new game-changer, enabling technology for tuneable, adaptive and cognitive artificially engineered metasurfaces and metamaterials. These sensorial surfaces and functional skins are based on nano-antennas and nano-resonators organized in hierarchical architectures, where electric, magnetic, optical, thermal and mechanical actuations mechanism can be used to tune their performances. Such structures can perform any type of electromagnetic wave-front manipulation allowing new forms of communication, sensing and also new ways of performing mathematical operations directly on light. A European consortium is proposing this technology for the next EU Flagship program.

High spatial resolution hyperspectral camera based on a continuously variable filter

Dr.-Ing. Oliver Pust, Director Sales and Marketing, Delta Optical Thin Film A/S

A small, lightweight, and inexpensive hyperspectral camera based on a continuously variable filter close to the focal plane array (FPA) is described. The use of a full-frame sensor allows large coverage with high spatial resolution at moderate spectral resolution. The spatial resolution has been maintained using a tilt/shift lens for chromatic focusing corrections. The trade-offs of positioning the filter relative to the FPA and varying the f-number have been studied. Calibration can correct for artefacts such as spectral filter variability. Reference spectra can be obtained using the same camera system by imaging targets over homogeneous areas. For textured surfaces, the different materials can be separated by using statistical methods. accurate reconstruction of the sparse spectral image data is demonstrated.

Cost effective quality control of LEDs and laser systems in engineering and production

Markus Revermann, Sales Manager, Ophir Spiricon Europe GmbH

Rising customer expectations and the increase of public regulations lead to a higher demand for quality control in production of LEDs and laser systems. Even though LED light does differ a lot from a laser beam, we will present some measurement devices that can be used for both product categories. In order to efficiently measure total flux, color and flicker of LEDs luminaires we will introduce a brand new technology that is ideally suited for the use in production environment. We will explain the key functions needed when it comes to automated measurement of high power laser beams in harsh industrial surroundings.
