technical field [0001] The invention relates to the field of microwave photon signal generation, in particular to a photoelectric oscillator based on an on-chip integrated system and a method for generating microwave signals. Background technique [0002] With the continuous improvement of communication rate and communication capacity, the microwave signal frequency band used for communication is also increasing. However, limited by the processing speed of electronic devices and the transmission loss of high-frequency microwave signals, microwave technology encounters great resistance in the process of expanding to high frequencies. Microwave photonics uses photon technology to generate, process and transmit microwave signals.

AI Technical Summary

Problems solved by technology

At present, mature optoelectronic oscillators generally require a long optical fiber as a delay energy storage device to improve the quality of the generated signal, but the large size of the long optical fiber limits the use of optoelectronic oscillators

However, the quality of the generated microwave signal is also limited due to the difficulty in achieving a large on-chip delay for the optoelectronic oscillator based on the integrated device on the chip.
