Abstract
An optical device includes a micro-ring laser having a first cavity and a waveguide having a second cavity. Light emitted by the micro-ring laser can be configured to circulate the first cavity. The second cavity can be defined by a first reflector. The first reflector can be a Distributed Braggs Reflector. The waveguide and the micro-ring laser can be positioned with a distance therebetween that allows at least some of the light emitted by the micro-ring laser to leak into the second cavity from the first cavity. The leaked light can reflect off the first reflector of the waveguide.
Claims15
An optical device, comprising:
- a micro-ring laser having a first cavity, wherein light emitted by the micro-ring laser is configured to circulate the first cavity;
- and
- a waveguide having a second cavity defined by a first reflector, wherein the waveguide and the micro-ring laser are positioned with a distance therebetween that allows at least some of the light emitted by the micro-ring laser to leak into the second cavity from the first cavity and reflect off the first reflector,
- wherein the first reflector is a Distributed Braggs Reflector (DBR) that is associated with at least one side-mode peak, and the optical device is tuned to align at least one modulation side-band of the micro-ring laser with the at least one side-mode peak.
