Bloch surface waves (BSWs) are surface electromagnetic waves excited at the interface between a truncated periodic dielectric multilayer and a surrounding medium. This particular solution to the Maxwell equations in stratified media has been known since th ...
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 ...
Laser-induced forward transfer (LIFT) is a versatile organic light-emitting diode (OLED) pixel deposition process, but has hitherto been applied exclusively to polymeric materials. Here, a modified LIFT process has been used to fabricate small molecule Alq ...
Trapping of mesoscopic particles by optical forces usually relies on the gradient force, whereby particles are attracted into optical wells formed by landscaping the intensity of an optical field. This is most often achieved by optical Gaussian beams, inte ...
Because of their biocompatibility and unique magnetic properties, superparamagnetic iron oxide nanoparticles NPs (SPIONs) are recognized as some of the most prominent agents for theranostic applications. Thus, understanding the interaction of SPIONs with b ...
The goal of this project is to demonstrate by simulations the relevance of fabricating nanowired structures for integrated optical applications. Indeed, subwavelength nanostructures present the advantage of guiding consistently the light, while having also ...
Optical devices that do not employ magneto-optics materials or non-linear effects to achieve non-reciprocal light propagation. The optical devices are compatible with the fabrication of monolithic photonic integrated circuits such as silicon-on-insulator p ...
With a span as long as the history of polymer science itself, post-polymerization modification represents a versatile platform for the preparation of diversely functionalized polymers from a single precursor. Starting with the initial efforts by Staudinger ...
In this thesis, the development, design, fabrication and characterization of three innovative laser beam shaping, homogenizing and speckle reduction devices are reported. Typical beam shaping devices are static and not easily adaptable to a large variety o ...
For decades, the size-dependent optical properties of semiconductor nanocrystals have been explored to elucidate their fundamental electronic nature and develop their potential for optoelectronic devices. Recently, substitutional doping has emerged as a co ...
