CHALCOGENIDE GLASS-SILICON HYBRID WAVEGUIDE AND RESONATORS FOR WAVELENGTH CONVERSION

摘要

The aim of the invention is to increase the efficiency of degenerate four-wave mixing in SOI waveguides. For this purpose, slotted silicon (Si) waveguides which lie on a silicon oxide layer (SiO₂) and which are infiltrated with and covered by chalcogenide glasses (e.g. As²S³) are used. In order to increase efficiency, said waveguides were shaped to annular or racetrack resonators. Chalcogenide glasses were chosen due to their high optical third-order nonlinearity (X (³)).
