Unidirectional emission in asymmetric Reuleaux triangle 2-D microcavity laser

Abstract

In an asymmetric Reuleaux triangle microcavity laser, we experimentally confirm that the laser unidirectionally emits at a single window. In this shape, because the quality factor of the clockwise traveling wave is higher than that of the counter clockwise one, the clockwise traveling wave emits at a single window. © 2015 IEEE.
