Latest Patents
Okawachi's latest patents include "Low frequency wave generation via optical frequency division" and "Tunable optical frequency comb generator in microresonators." The first patent describes systems, methods, and devices for generating tunable low frequency signals, such as microwave and radiofrequency signals. It involves a first waveguide in optical communication with a first ring resonator, which can receive a light input and generate frequencies through optical parametric oscillation. A second waveguide with a second ring resonator can receive these frequencies and synchronize them optically to produce a low frequency signal. Additionally, heating elements can be connected to each ring resonator to tune the resonators and minimize noise associated with the low frequency signal. The second patent outlines optical frequency combs and related methods, devices, and systems. It describes a device that includes a waveguide configured to optically couple to an optical source and at least one optical resonator. The resonator can be tuned to generate an optical frequency comb based on mode interaction between two different modes of the resonator.
