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.
