Higher Harmonics Generation for Instant Pathology

Successful surgical treatment of cancer depends on a balance between removing as much as possible of the cancerous tissue while minimizing damage to healthy tissue. Currently, surgeons mainly rely on pre-operatively determined tumour positions and intraoperative visual examination to decide on the extent of resection. Unfortunately, this challenges complete removal of cancerous tissue, which leads to recurrence of disease and the need for repeated surgery or additional treatment. In this talk I will show how we develop Second and Third Harmonics Generation (SHG/THG) imaging for non-invasive, real-time, ex-vivo and in-situ optical analysis of tissue in the operating room, augmented by automatic image analysis.

Managing the solar spectrum at sub-wavelength scales

Semiconductor nanowires (NWs) are promising building blocks for next generation solar energy conversion at low cost. NW ensembles constitute a new class of metamaterial. While the photonic properties of small dielectric structures have been widely studied within the framework of Mie scattering, coupling to poorly confined waveguided modes drives the absorption spectrum in NWs. This work investigates how vertical NWs interact with light from both theoretical and experimental methods. We discuss completely new designs of solar cells, that are not possible in the bulk form. Finally, we show how the impact of this strong light-matter interactions goes beyond solar applications.

Integrated Photonics - Enabler of the next Societal Revolution

The developments of solid state laser and Photonic Integration technologies are enabling a next societal revolution. Photonic Integrated Circuits (PICs) and Integrated Photonic-Electronic Systems are core to the development of low cost systems for processing of massive amounts of data at low energy per bit and at very high data rates. Furthermore, this technology enables the development of a wide range of chip based new sensor systems with very high performance. These systems can be produced in large quantities at relatively low cost. Photonic Integration will be a key enabling technology for solving major societal challenges faced today.

Optical Sensors for Medical Applications

Optical sensors are increasingly applied throughout many disciplines. Medical Photonic sensors form a growing market, and we take a peak at some interesting trends, in particular on hyperspectral imaging and wearable medical photonics.

Integrated 4D Tomographic Mouse Imaging from 1eV to 1 MeV

We developed a 4D scanner to -for example- see various functions of neurons and detailed brain vasculature in action, obtain cardiac structure, mechanical parameters and various cell functions in a single scan, and map integrated detailed dynamics of contrast agents, pharmaceuticals and indicators of heterogeneous tumour response. This  integrated imaging platform with A) combined 0.14 mm resolution SPECT & 0.6 mm PET with concurrent multi-tracer and ultra low dose & sub-second dynamic imaging capabilities  B) ultra-high performance X-ray CT and C) Cherenkov, fluorescence & bioluminescence tomography. This highly adaptive and versatile nuclear, optical and structural imaging technologies will be explained along with many scientific applications of world wide users as well as  results of translating our  imaging technologies into clinical imaging.

Time-resolved fluorescence to prevent organ failure

Time-resolved fluorescence can address some of the biggest problems facing physicians. Patients die when organs fail. And organs fail when cells lack oxygen. So doctors have long wanted to measure oxygen within cells rather than only in blood. Based on the invention of Dutch anesthesiologist Egbert Mik, Photonics Healthcare provides the first CE marked patient monitor that measures in active tissue cells. Measuring where oxygen is needed allows doctors to assess if the cells can use enough oxygen and provides pre-emptive guidance for the therapies to prevent organ failure. And oxygen utilization is central to other clinical situations from wounds, to cancer, to surgeries to transplants.

Hybrid SEM-Raman microscopy: adding colours to gray

The analytical power of Raman microscopy has been integrated with scanning electron microscopy. The hybrid microscope system enables chemical analysis by optical spectroscopy correlated with morphological observations by electron microscopy. An explanation of the technology and applications in crystal analysis, plasmonics and biology will be presented. The new technology of hybrid SEM-Raman microscopy enables a versatile approach to a broad range of applications in material science.

Lensless imaging with extreme ultraviolet light

Lensless imaging is an elegant approach to microscopy, in which the image formation is achieved using computer algorithms rather than optical components. Such an approach enables high-resolution imaging with radiation for which there are no good-quality imaging optics available, such as extreme ultraviolet (EUV) and X-rays. Furthermore, it opens up the possibility of correcting optical aberrations in an imaging system by computational methods. I will explain the principles of lensless imaging and discuss some recent experimental results, including our efforts to develop an ultra-high-resolution microscope, using table-top coherent EUV sources based on a process called high-harmonic generation.

Challenges in the development and production of LED luminaires

Optical requirements of the LED system are based on the challenging demands concerning light quality, energy efficiency and optical safety. The lighting systems should deliver the right amount of light only where needed, and at the same time the well-being of the user needs to be guaranteed, when lighting is finally installed. The current trends in the lighting industry like dynamic lighting, first class colour quality, tuneable spectra and variable CCT dictate even more demanding development procedures. The lecture will cast some light on efficient, fast and accurate light measurement within the development process.
