Photonic crystals
The photonic crystal research in the institute for Optical and Electronic Materials is concentrated on the slow light effects in silicon line-defect waveguides as well as on tunable cavities in silicon and polymer photonic crystals. The electro optical tuning is achieved by functionalizing silicon photonic crystals with nonlinear polymers as cladding material or slot filling. The goal for the slow light waveguides is the realization of silicon line-defect waveguides with tunable time delay in the order of 1 nanosecond and tunable dispersion of several hundred picoseconds per millimeter. Periodical and chirped waveguides will be investigated in respect for their bandwidth, time delay, dispersion and tunability. Low voltage electro-optical modulators are going to be achieved with modulation frequency around 100 GHz. These modulators are based on slow light line-defect waveguides in Mach-Zehnder interferometers and on resonant photonic crystal cavities by the electro-optical shift of the phase shift or resonance frequency correspondingly. High Q photonic crystal cavities functionalized with polymers can be also used for tunable time delay.
