In this work planar and rib β-SiC-on-insulator waveguides were investigated. The waveguides were fabricated by two different methods. In the first a technological process similar to that of SIMOX was used, a buried SiO2 layer was formed by a two-step high-energy ion implantation of oxygen in SiC/Si wafers. For the second type of waveguides we used heteroepitaxy of SiC on SOI(SIMOX). The losses have been measured at 1.3 and 1.55μm. Rib waveguides were fabricated using dry-etching (RIE). These types of waveguides have great potential for high-speed silicon-based photonic devices compatible with silicon technology.
