Abstract
Laser feedback stabilization combined with isolation is provided in an integrated approach. The main element is a high quality factor resonator that acts as a circulator under high optical power due to the Kerr nonlinearity. This resonator can then be coupled to a laser or optical gain media to provide isolation and combined with a feedback path to stabilize the lasing mode.
Claims12
Apparatus comprising:
- a laser gain medium;
- a first optical ring resonator optically coupled to the laser gain medium, wherein an output optical path from the laser gain medium to an output of the feedback stabilized laser includes the first optical ring resonator;
- and
- a feedback path configured to return a predetermined fraction of output optical power to the laser gain medium, whereby a feedback-stabilized laser is provided;
- wherein the first optical ring resonator is a nonlinear resonator having unidirectional coupling to the laser gain medium such that back-reflection into the output of the feedback stabilized laser is suppressed by being off-resonance relative to the first optical ring resonator.
