System and method for generating photon dual-frequency comb based on double loop locking

Abstract

The invention relates to a system for generating a photon dual-frequency comb based on double loop locking. The system comprises an 8-transverse-shaped control loop, an incident signal source, a circulator, a coupler, two WDM wavelength division multiplexers, two IQ modulators and a semiconductor optical amplifier (SOA), the coupler is disposed at the ring junction of the 8-transverse-shaped control loop and is connected with the 8-transverse-shaped control loop, the SOA is arranged on the right ring of the 8-transverse-shaped control loop, the two WDM wavelength division multiplexers are respectively arranged at the two ends of the SOA, the two IQ modulators are symmetrically arranged on the two rings of the 8-transverse-shaped control loop, the incident signal source is connected with the port 1 of the circulator, and the port 2 of the circulator is connected with the coupler. The system and method for generating a photon dual-frequency comb based on double loop locking can obtain multiple groups of different photon dual-frequency combs, can obtain good spectral flatness, and are high in system integration so as to make up the defects of the limited frequency combs by adopting asingle modulator.

Description

technical field [0001] The invention relates to the field of optical frequency technology, in particular to a system and method for generating a photonic dual-frequency comb based on double-ring locking. Background technique [0002] An optical frequency comb (OFC) refers to a comb-like spectrum structure composed of dozens, hundreds of thousands or even millions of frequency spectral lines that are evenly spaced and have a coherent and stable relationship on the spectrum. Its original use was in the field of optical frequency measurements to provide a highly accurate time reference. With the development of its technology, optical frequency comb technology has also been well applied in optical arbitrary waveform generation, dense wavelength division multiplexing, etc. extensive attention. Especially in the case of the rapid increase of global broadband service traffic in recent years, in order to meet the higher requirements of access network and urban LAN network capacity...
