Today physicians are still severely hampered by the lack of precision of the needle tip location during a biopsy. Looking at lung cancers, 25% of the diagnoses suffer a false negative outcome through traditional biopsy methods. In the future, this can be avoided: for the first time, the European project InSPECT developed miniature spectrometers with integrated light sources enabling guided sensing. Ground-breaking was the fabrication of the reflective segmented diffractive gratings with VUB B-PHOT’s in-house polymer prototyping pilot line.

She is granted this prestigeous price for “introducing a disruptive model for the nonlinear process of Coherent Anti-Stokes Raman Scattering and employing it to conceptualize a novel cooling technique for Raman lasers. She also came up with a groundbreaking phase matching approach for on-chip nonlinear wavelength converters, enabling device manufacturing in photonic foundries with standard fabrication rules. Today she impacts mid-infrared solid-state laser development, and targets next‐generation nonlinear photonic devices based on graphene.” The Award ceremony will take place on June 24 at the World of Photonics Congress in Munich.

In his PhD thesis, Gebirie Yizengaw realized a miniaturized multichannel multiresolution imaging system in which the different channels have different Fields Of View (FOV) and angular resolutions. His imaging system is therefore able to capture, at the same time, images of an individual scene with different magnifications. It also enables to process the different images with different image processing algorithms. For example a motion detection algorithm could be implemented on the wide FOV - low resolution image, whereas a face detection algorithm could be used for the narrow FOV -high resolution image.

It is generally acknowledged that a human observer will no longer perceive speckle in projected images once the speckle contrast becomes sufficiently small. However, up until now, no in-depth investigation on the perception of speckle by human observers has been investigated.

On 21 October 2014, Yannick Lefevre defended his PhD thesis titled: “New Perspectives on Four-Wave Mixing in Silicon Waveguide Structures.” Optical four-wave-mixing processes are nonlinear mixing interactions that enable a wide variety of photonic functionalities, including wavelength conversion, parametric amplification, all-optical switching, and signal regeneration. In silicon waveguide structures, these interactions can be triggered at low optical powers due to the tight optical confinement offered by these structures.
