Abstract
An optical frequency comb generation system comprises an optical waveguide, which in turn comprises a length defining an elongated direction of the waveguide, and first and second reflector portions along the length and arranged to reflect light within the waveguide. A weak reflector portion is between the first and second reflector portions along the length of the waveguide and has a reflectivity less than the reflectivity of the first and second reflector portions. The weak reflector portion is arranged to shift wavelengths of resonances of light within the waveguide.

An optical frequency comb generation system, comprising:
- an optical waveguide comprising:
- a length defining an elongated direction of the waveguide,
- first and second reflector portions along the length and arranged to reflect light within the waveguide, and
- a weak reflector portion between the first and second reflector portions along the length of the waveguide and having a reflectivity less than the reflectivity of the first and second reflector portions, wherein the weak reflector portion is arranged to shift wavelengths of resonance of light within the waveguide.
An optical device, comprising:
- an optical waveguide with a length defining an elongated direction of the waveguide and an optical resonator, the optical resonator comprising:
- first and second reflector portions along the length and arranged to reflect light within the waveguide, and
- a weak grating between the first and second reflector portions along the length of the waveguide and having a reflectivity less than the reflectivity of the first and second reflector portions, wherein the weak grating is arranged to shift wavelengths of resonances of light within the waveguide.
A method of generating an optical frequency comb, comprising:
- receiving light at a first reflector portion along a waveguide of a light resonator;
- reflecting the light at the first reflector portion, comprising dividing the light into multiple light beams with different resonant wavelengths, wherein the first reflector portion has a first reflectivity;
- receiving reflected light from the first reflector portion at a weak reflector portion, wherein the weak reflector portion is arranged to shift wavelengths of the resonance of the reflected light and has a weak reflectivity less than the first reflectivity;
- reflecting light with shifted resonance wavelengths received from the weak reflector portion at a second reflector portion having a second reflectivity greater than the weak reflectivity;
- and
- generating an optical frequency comb by using the light with the shifted resonance wavelengths.
