Paper Abstract

Submicron silicon-on-insulator (SOI) optical waveguides, which has ultra-high index contrast and ultra-small cross section, provide a very promising way to realize nano-photonic integrated circuits (PICs) with high integration density. Mode conversion and coupling play an important role for realizing various functionality elements. In this paper, a review is given for our recent work including the following parts. First, we discuss the polarizationdependent mode conversion happening in an adiabatic submicron SOI optical waveguide tapers and the application to realize polarization rotation with simple fabrication processes. Second, the mode coupling/conversion in an asymmetrical directional coupler (ADC) is summarized. The application for ADCs includes the realization of ultrasmall polarization-beam splitters (PBS) as well as ultra-compact broadband mode multiplexers (which is very important to enable ultra-high speed optical interconnects with a multimode optical waveguide).
