Abstract
Embodiments of the present disclosure disclose an optoelectronic oscillator including an optical chip and a microwave chip. The optical chip is implemented by fabricating different optoelectronic devices on an integrated optical substrate, comprising: a laser assembly; a mode selection device coupled to the laser assembly, and configured to receive the laser and perform mode selection; an optical delay module coupled to the mode selection device; and a detector coupled to the optical delay module. The microwave chip is a microwave integrated circuit formed by fabricating microwave elements on a semiconductor substrate, comprising: a microwave processing circuit configured to receive microwave signal and perform signal processing; a coupler coupled to the microwave processing circuit, and configured to provide a part of the microwave signal to a phase shifter and output the other part thereof; and a phase shifter configured to feed the phase-shifted microwave signal to the laser assembly.
