Abstract

The present invention relates to the microwave signal generation technology field, especially to a tunable optoelectronic oscillator based on cross phase modulation. The tunable optoelectronic oscillator based on cross phase modulation comprises a narrow linewidth laser; light output by a high-power narrow linewidth laser passes through a dual-drive electrooptic intensity modulator, an optical coupler 1, a Mach-Zehnder interferometer and a non-linear fiber loop mirror in order; the Mach-Zehnder interferometer is formed by an optical coupler 2 and an optical coupler 3; the non-linear fiber loop mirror is formed by a wavelength division multiplexer, a high-nonlinear fiber and an optical coupler 4; light output by the optical coupler 3 passes through a photoelectric detector, an amplifier, a band-pass filter, a 10dB coupler and a 3dB bridge; and the 3dB bridge is connected with the dual-drive electrooptic intensity modulator to form an annular resonator. The tunable optoelectronic oscillator based on cross phase modulation also comprises control light, and the control light enters the wavelength division multiplexer through an erbium-doped optical fiber amplifier and a polarization controller in order and enters the non-linear fiber loop mirror through the wavelength division multiplexer.

Description

technical field [0001] The invention relates to the technical field of microwave signal generation, in particular to a tunable photoelectric oscillator based on cross-phase modulation. Background technique [0002] Photoelectric oscillator is a kind of photo-generated microwave technology that has attracted wide attention in recent years. The performance of the high-frequency signal generated by the photoelectric oscillator is independent of frequency, so it can generate microwave signals with high spectral purity, high stability and low phase noise, and has the characteristics of generating optical and electrical signals, and is widely used in wireless communication, Military radar, light wave communication and other fields, however, the actual application requirements focus more on the tunability of optoelectronic oscillators. [0003] The traditional tunable photoelectric oscillator mainly has the following types: one is to use an electric filter with a fixed center freq...
