Optical frequency references are devices providing well-defined and stable optical frequency responses to incoming radiation for applications such as high-precision spectroscopy and optical fibre communications. To stabilise the emission frequency of laser ...
Micro/nano robots have the potential to revolutionize many aspects of medicine. These untethered, wirelessly controlled and powered devices will make existing therapeutic and diagnostic procedures less invasive and will enable new procedures never before p ...
Following rapid developments in biotechnology and medicine, optical sensing promises to be extremely important in various applications such as drug discovery, environmental monitoring, etc. Refractive index (RI) based optical sensing is straightforward to ...
We study the reflection of a tightly focused Gaussian beam off a near symmetric resonant tunneling structure comprising two identical coupled waveguides. The coupled waveguides are loaded on each side by a spacer layer and a high index prism. Reflection of ...

This work presents the development of two MEMS programmable diffraction gratings designed for spectroscopic applications in the visible, near- and mid-infrared. These devices have been developed to limit distortion of their optical surfaces at rest and thr ...
Batteries, fuel cells and solar cells, among many other high-current-density devices, could benefit from the precise meso-to macroscopic structure control afforded by the silica sol-gel process. The porous materials made by silica sol-gel chemistry are typ ...
Efficient light management is one of the key issues in modern energy conversion systems, be it to collect optical power or to redistribute light generated by high power light emitters. This thesis touches mainly on the subject of efficient light redistribu ...
A plasmonic slot waveguide excited by evanescent wave coupling of a silicon strip waveguide is studied to be used as a label-free biosensor. The plasmonic slot waveguide enables strong electric-field enhancement in a small volume inducing higher interactio ...
Like photonic crystals have revolutionized the way of manipulating optical waves at the sub-micron scale, phononic crystals have more recently played similar decisive role for sound waves, or more generally elastic waves. Then, the idea of coupling light a ...
Micro-optics describes a family of elements and systems fabricated by modern micromachining. Optical structures with nearly arbitrary shapes and dimensions down to the nanometer can be realized offering a large degree of freedom for the design. The progres ...
