摘要/Abstract

摘要： 本工作基于全光纤化的干涉结构实现了高信噪比的单频微波信号产生, 并通过抑制相干光信号噪声降低了微波信号的噪声边带。该微波信号由窄线宽布里渊泵浦光与其生成的斯托克斯光干涉所产生。首先基于受激布里渊散射 (stimulated Brillouin scattering, SBS) 效应将产生的斯托克斯光的线宽压窄至~43 Hz, 对应频率噪声的降低; 再利用级联SBS效应中的噪声动力学原理, 将一阶斯托克斯光的相对噪声强度降低了 21 dB/Hz。通过降低相干信号光的频率噪声和强度噪声, 使得微波信号的噪声边带被完全抑制, 表现为在一阶布里渊频移9.415 GHz处, 微波信号的信噪比从48 dB被提升至84 dB, 同时在二阶布里渊频移18.827 GHz 处产生信噪比为70 dB的微波信号。这种具有窄线宽、高信噪比的微波信号可以为雷达、卫星通信等应用提供更高的探测分辨率和传输效率。

Abstract: In this work, the generation of high signal-to-noise ratio (SNR) single-frequency microwave signal without noise sidebands is demonstrated based on the interaction of integrated all-fiber lasers. The microwave signals are generated by the interference between a narrow linewidth Brillouin pump light from a single-frequency laser and the Stokes light generated by it. Firstly, the linewidths of the Stokes lights are compressed to ~ 43 Hz based on the stimulated Brillouin scattering (SBS) effect, which ensures that the frequency noise is as low as possible. And then, the relative intensity noise (RIN) of the firstorder Stokes light is reduced by 21 dB/Hz based on the noise dynamics principle in cascaded SBS effect. By simultaneously reducing the frequency noise and the intensity noise of the coherent signals, the noise sidebands of microwave signals are completely suppressed. As result, the SNR of the microwave signal is improved from 48 dB to 84 dB at the first-order Brillouin frequency shift of 9.415 GHz. Meanwhile, a microwave signal with a SNR of 70 dB is generated at the second-order Brillouin frequency shift of 18.827 GHz. This kind of microwave signals with narrow linewidth and high SNR can provide higher detection resolution and higher transmission efficiency for applications on radar, satellite communication and so on.
