摘要
光电振荡器(OEO)作为微波信号源是微波光子学领域的研究热点,提出并理论分析了一种基于受激布里渊散射(SBS)效应和载波相移单边带调制的频率和相位均可调谐的五倍频OEO。在该结构中,利用级联调制器结构产生5个功率相等、频率间隔相同的光作为泵浦光,并通过布里渊增益损耗补偿原理得到五倍频OEO。利用布里渊波长依赖特性得到了频率可调谐的微波信号,通过调节双平行马赫曾德尔调制器实现了输出微波信号的相位可调谐。所设计的OEO可以输出高频率微波信号,频率调谐范围为44.00~47.25 GHz,并在频率可调谐的基础上实现了0°~360°的相位可调谐。
Optoelectronic oscillator(OEO),a microwave signal source,is a popular research topic in microwave photonics.A quintuple OEO with tunable frequency and phase is proposed and theoretically analyzed,which is based on the stimulated Brillouin scattering(SBS)effect and carrier phaseshifted singlesideband modulation.In this structure,a cascade modulator structure is used to generate five lights with the same power and frequency interval as the pump lights,and then the quintuple OEO is obtained by the Brillouin gainloss compensation principle.The frequencytunable microwave signal is obtained by using the Brillouin wavelengthdependent property,and phasetunable output microwave signal is obtained by adjusting the dualparallel MachZehnder modulator.The designed OEO can output highfrequency microwave signals with a frequency tuning range of 44.00-47.25 GHz,and on this basis,it can achieve a tunable phase range of 0°-360°.
