Coupled opto-electronic oscillators with a whispering-gallery-mode (WGM) optical resonator inside the laser cavity to produce oscillation signals out of the optical spectral range, e.g., RF or microwave frequencies.
This application describes devices and techniques for using microwave or RF resonators to provide DC bias, DC blocking, and impedance matching to microwave or RF devices. Both planar and non-planar implementations may be used.
