Paper Abstract

Novel bi-directional propagation is observed in a shallow-etched bending ridge waveguide. The lasing light propagates in two different paths, straight way and bending way. The far-field pattern is quite different before and after the lasing condition is reached. Emission spectra of light emitted from two facets are also different. This is because the bidirectional guided effect of lasing mode occurs.
