Abstract

We study directional bistability in hybrid silicon microring lasers and demonstrate an unidirectional laser. Unidirectional emission is achieved by integrating a passive reflector that feeds laser emission back into laser cavity to introduce extra unidirectional gain. We show that the length of the passive reflector is a critical parameter in determining the lasing behavior.
