Unidirectional ring lasers

摘要

A laser includes an active ring, a passive waveguide, and a reflector. The active ring is to generate light. The passive waveguide is associated with the active ring to capture generated light. The reflector is associated with the passive waveguide to cause captured light from the waveguide to be coupled into the active ring to trigger domination of unidirectional lasing in the active ring to generate light.

1. A laser, comprising:
an active ring to generate a light; a passive waveguide associated with the active ring for capturing a captured light of the light that is generated; and a reflector associated with the passive waveguide to cause the captured light from the waveguide to be coupled into the active ring to trigger a domination of unidirectional lasing of the light in the active ring, wherein the reflector is tunable to adjust a reflection bandwidth of a lasing wavelength associated with the active ring.
