Abstract
Generally discussed herein are systems, devices, and methods for locking an optical frequency comb. A device may include comb error measurement and control circuitry to receive a beat tone and carrier envelope offset of an optical frequency comb and provide a fast and slow repetition rate control and a fast and slow carrier envelope offset control. The repetition rate controls and carrier envelope offset controls to control actuators of an optical frequency comb generator.

A system comprising:
- error measurement and control circuitry configured to receive a first signal comprising a beat tone and a carrier envelope offset corresponding to an optical frequency comb and a second signal comprising the carrier envelope offset and provide a fast repetition rate control, a slow repetition rate control, a fast carrier envelope control, and a slow carrier envelope control for locking an optical frequency comb, wherein the error measurement and control circuit includes:
- comb error measurement circuitry configured to receive the first and second signal, and to provide a beat tone error and a carrier envelope offset error;
- repetition rate control circuitry configured to receive the beat tone error signal and to provide a fast repetition rate control and a slow repetition rate control for locking the beat tone of the optical frequency comb;
- and
- carrier envelope offset control circuitry configured to receive a carrier envelope offset error and to provide a fast envelope offset control and a slow envelope offset control for locking the carrier envelope offset of the optical frequency comb.
A method for locking an optical frequency comb comprising:
- receiving, using error measurement and control circuitry, a first signal comprising a beat tone and a carrier envelope offset corresponding to the optical frequency comb and a second signal comprising the carrier envelope offset;
- determining, using comb error measurement circuitry and the first and second signal, a beat tone error and a carrier envelope offset error;
- providing, using repetition rate control circuitry and the beat tone error, a fast repetition rate control and a slow repetition rate control for locking the beat tone of the optical frequency comb;
- and
- providing, using carrier envelope offset control circuitry and the carrier envelope offset error, a fast repetition rate control and a slow repetition rate control for locking the carrier envelope offset of the optical frequency comb.
At least one non-transitory machine-readable medium the machine-readable medium including instructions, which when performed by a machine, cause the machine to performs operations for locking an optical frequency comb, the operations comprising:
- receiving, using error measurement and control circuitry, a first signal comprising a beat tone and a carrier envelope offset corresponding to the optical frequency comb and a second signal comprising the carrier envelope offset;
- determining, using comb error measurement circuitry and the first and second signal, a beat tone error and a carrier envelope offset error;
- providing, using repetition rate control circuitry and the beat tone error, a fast repetition rate control and a slow repetition rate control for locking the beat tone of the optical frequency comb;
- and
- providing, using carrier envelope offset control circuitry and the carrier envelope offset error, a fast repetition rate control and a slow repetition rate control for locking the carrier envelope offset of the optical frequency comb.
