Characteristics of microring/racetrack resonators, in submicron SOI rib waveguides, have been investigated. The effects of waveguide dimensions, coupler design, roughness, and oxide cladding are considered. Moreover, guided mode, loss and dispersion of such waveguides are analyzed.
Recent progresses of Si-based photonic devices are reviewed in the paper. The experimental results in our laboratory, including Si-based photodiode, SOI sub-micron waveguide, high rate optical switch and coupler with ?? of 25% are present.
