Paper Abstract

A bending directional coupler is presented to enhance the evanescent coupling between a compact deeply-etched III-V/Si hybrid microring laser and its small Si bus waveguide. With the present design, one could realize a sufficient evanescent coupling between the III-V/Si hybrid microring even when the gap between the microring and the bus waveguide is relatively large gap (~ 400nm). This makes the fabrication easier.
