Abstract

The invention discloses a microwave photon up-conversion device and method based on a photoelectric oscillator and belongs to the technical field of microwave photonics. The device is composed of a laser source, a first coupler, a first circulator, a first high nonlinearity dispersion displacement optical fiber, an erbium-doped optical fiber amplifier, a first photoelectric detector, a second coupler, a first Mach-Zehnder modulator, a first microwave signal source, a first direct current voltage-stabilized power supply, an optical filter, a second Mach-Zehnder modulator, a second direct current voltage-stabilized power supply, a second circular, a second high nonlinearity dispersion displacement optical fiber, a second photoelectric detector, a microwave amplifier, a double-parallel Mach-Zehnder modulator, a third direct current voltage-stabilized power supply, a fourth direct current voltage-stabilized power supply, a fifth direct current voltage-stabilized power supply, an optical isolator and a spectrum analyzer. A Brillouin frequency shift value f of the high nonlinearity optical fiber is 9.2GHz, and a signal with frequency of f<m> can be up converted to f<m>+18.4GHz, so alow quality and low frequency intermediate signal is converted into a high quality and high frequency signal.

Description

technical field [0001] The invention belongs to the technical field of microwave photonics, and in particular relates to a microwave photon up-conversion device and method based on a photoelectric oscillator. Background technique [0002] Microwave / millimeter wave signal sources with high spectral purity and low phase noise play a very important core role in wireless communication, radio frequency transmission over optical (RoF), radar and other systems, so in recent years, research on how to generate high-quality microwave signals The signal source has become a research hotspot. The traditional method of generating microwave signals is through electrical means, but the electronic bottleneck effect of electrical devices and tuning bandwidth and other issues have made the research on the generation of microwave signals by electrical methods gradually reach the bottleneck. In the field of photonics, photon technology has the advantages of high processing rate, low transmissio...
