Hybride Mikrophotonik

The goal of the project "Hybride Mikrophotonik" is to design and realize a highly integrated microphotonic component permitting efficient amplification, compensation and distribution of optical data signals. This task is carried out in cooperation with two other departments at TUHH, namely Micro Systems Technology and Materials in Electrical Engineering and Optics. Our group is concerned with design, verification and characterization of the components.

In particular, novel trench bulge waveguides based on aluminum oxide are theoretically analyzed with regards to their polarization and guiding properties, because this technology promises to achieve very low propagation losses. Furthermore, components like Multimode Interference couplers are designed and characterized experimentally. The goal is to realize a thermally tunable, highly integrated chromatic-dispersion compensator for optical fiber spans.

As a concept for amplification in integrated-optical circuits, Raman amplification in silicon-on-insulator (SOI) waveguides is investigated.
