Abstract

A microwave photon trap wave apparatus with a silicon-based self-coupling micro ring resonant cavity relates to the technical field of optical fiber communication and comprises a to-be-processed signal generation module, a microwave photon trap wave module and a processed-signal feedback module. A to-be-processed photon signal is generated by the to-be-processed signal generation module and then input by an input end of the microwave photon trap wave module; and an output end of the microwave photon trap wave module outputs a processed signal via the processed-signal feedback module.. Limitations on processing speed and adjusting range can be removed and a solution scheme is provided for realization of a filtering function of a dynamic broadband microwave signal processing system.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a microwave photon trapping device based on a silicon-based self-coupling microring resonator cavity. Background technique [0002] In broadband access networks, phased array radar and satellite communication systems, the spectrum components of actual microwave signals usually contain not only the frequency components that people need, but also some components caused by local oscillator leakage, sideband leakage, pilot signals and other interference signals. the resulting frequency components. In order to improve the signal-to-noise ratio of microwave signals, it is usually necessary to filter out or suppress these interference frequency components in actual signal processing, and the device that realizes this function is a microwave notch device. Traditional electric microwave filters are based on integrated circuits composed of resistors, inductors, and cap...
