Abstract
The present invention provides octave-spanning optical frequency combs. The octave-spanning optical frequency combs employ microresonators having improved stability using a smaller form factor. In some embodiments, the octave-spanning optical frequency combs are fabricated using aluminum nitride (AlN). AlN is a more robust Kerr material for generating octave-spanning soliton comb (e.g., 1.5 octaves or more).
Claims21
An octave-spanning optical frequency comb device, comprising:
- an optical pathway having at least one entry and at least one exit;
- at least one laser source positioned at the at least one entry;
- and
- at least one microring resonator positioned adjacent to the optical pathway between the at least one entry and the at least one exit, wherein the at least one microring resonator comprises aluminum nitride (AlN) and wherein the device comprises an intrinsic optical Q factor of at least 3,000,000.
