Abstract

The invention discloses a device and method for generating a four-frequency-doubling signal and realizing microwave photon phase shift based on a double-parallel modulator, and relates to the technical field of microwave and optical communication. The device and method are mainly applied to microwave photon signal processing. As shown in figure, the device comprises an adjustable laser source (TLS), a dual-parallel modulator (DPMZM), an erbium doped fiber amplifier (EDFA), an optical loop (OC), a Prague fiber grating (FBG), a Faraday rotating mirror (FRM), a polarization controller (PC), a polarizer (Pol) and a photoelectric detector (PD). According to the method, a positive and negative two-order band optical signal for orthogonal polarization multiplexing is obtained by using DPMZM, FBGand FRM, and the 360-degree continuous phase shift while keeping basically unchanged amplitude of a microwave signal is achieved. In addition, the scheme further has the advantages of wide tuning range, simple structure, strong operability, and can be used for multi-channel applications.

Description

technical field [0001] The invention relates to the technical fields of optical communication and microwave technology, in particular to generating quadrupled frequency signals based on dual parallel modulators and realizing phase shifting of microwave photons in the optical communication technology. Background technique [0002] Microwave photonics is a technology that combines microwave and photonics in recent decades. It uses photonics technology to generate, transmit and process microwave signals, aiming to overcome the electronic bottlenecks of traditional microwave technology in terms of processing speed and transmission bandwidth.
