Low Frequency Wave Generation Via Optical Frequency Division

A method for generating tunable, low frequency signals, comprising:

• receiving a light input on a device, wherein the light input comprises a plurality of frequencies, and the device comprises a first waveguide in optical communication with a first ring resonator, and a second waveguide in optical communication with a second ring resonator;
• pumping the light input through the first waveguide to generate a first frequency and a second frequency via optical parametric oscillation (OPO);
• pumping the first frequency and the second frequency through the second waveguide to optically synchronize the frequencies via optical frequency division (OFD);
• generating a synchronized low frequency signal;
• and
• thermally tuning at least one of the first ring resonator and the second ring resonator to reduce noise associated with the low frequency signal.
