Direct modulation type multi-channel collaborative reconfigurable microwave photon acquisition chip

Abstract

The invention discloses a direct modulation type multi-channel collaborative reconfigurable microwave photon acquisition chip, which is characterized in that a multi-channel acquisition chip is constructed in a wavelength division multiplexing mode based on high-density integration of multiple paths of parallel DMLs (Division Multiplexing Language); then, external light injection locking is combined to obtain multiple paths of coherent output wavelengths, and multi-channel collaborative acquisition is realized; the acquisition channels are divided into two groups, the first group of DML acquisition channels are directly combined and output by the MMI type combiner, and multi-channel collaborative acquisition is supported; the second group of DML outputs are connected with an on-chip micro-ring resonant cavity processing module; and the filtering characteristic of the micro-ring is adjusted based on the thermo-optic effect, dynamic wavelength channel selection is achieved, and the reconfigurable multi-channel collection function is supported. The chip has the advantages of simple implementation, dense multi-channel collaborative acquisition, dynamic reconfiguration and the like, and has important application in optical communication, photoelectric signal processing and other systems.
