Latest Patents
Tetsumoto holds a patent for a "Compact microresonator frequency comb." This invention encompasses systems and methods for precision control of microresonator (MR) based frequency combs. The patent details the implementation of optimized MR actuators or modulators to control long-term locking of carrier envelope offset frequency, repetition rate, or resonance offset frequency of the MR. Additionally, MR modulators can be utilized for amplitude noise control. The parameters of the MR can be locked to external reference frequencies, such as a continuous wave laser or a microwave reference. This innovation aims to reduce cross talk between MR parameters, facilitating long-term locking. Furthermore, the MR can be locked to an external two-wavelength delayed self-heterodyne interferometer for low noise microwave generation. The MR-based frequency comb can be tuned by a substantial fraction or more of the free spectral range (FSR) via a feedback control system. Scanning MR frequency combs have applications in dead-zone free spectroscopy, multi-wavelength LIDAR, high precision optical clocks, and low phase noise microwave sources.
