Interferometric resonator optical gyroscope with optical frequency comb

A method for operating an interferometric resonator optical gyroscope, the method comprising:

• generating, with an optical frequency comb generator, an optical frequency comb;
• transmitting a first optical signal and a second optical signal from the optical frequency comb;
• coupling the first optical signal into an optical resonator in a first direction;
• coupling the second optical signal into the optical resonator in a second direction;
• coupling the first and second optical signals out of the optical resonator;
• determining an extent of interference between the first and second optical signals;
• determining a rotation rate based on the extent of interference.

A program product comprising a non-transitory processor-readable medium on which program instructions configured to be executed by at least one processor are embodied, wherein by executing the program instructions, the at least one processor is configured to:

• receive a signal corresponding to an optical signal after propagating in an optical resonator of an interferometric resonator optical gyroscope;
• determine an intensity corresponding to the signal;
• determine at least one parameter of an optical frequency comb based on the intensity;
• and
• control an optical frequency comb generator of the interferometric resonator optical gyroscope used to generate the optical frequency comb based on the determined at least one parameter.
