Dispersion in photonic crystals

Abstract: Investigations on the dispersive properties of photonic crystals, modified scattering in ring-resonators, monolithic integration of vertical-cavity surface-emitting lasers and advanced data processing techniques for the finite-difference time-domain method are presented.Photonic crystals are periodic mesoscopic arrays of scatterers that modify

Ultra-high-Q inverted silica microtoroid resonators monolithically integrated into a silicon photonics platform

Summary: This work reports on the design, fabrication and the optical characterization of a new singular type of microtoroid high-quality silica resonator, which is monolithically coupled to on-chip silicon nanowire waveguides. In order to enable monolithic waveguide coupling, the microtoroid
