本文首次提出并实现了一种具有鉴频鉴相器和单边带混频器的高集成度光锁相环。设计、制作和测试了一个光子集成电路（PIC）和一个电子集成电路（EIC）。PIC在InGaAsP/InP平台上集成了一个宽调谐采样光栅分布式布拉格反射器激光器，一个光学90度混合器和四个高速光电探测器。EIC增加了一个单边带混频器和一个数字相位/频率检测器，以提供-9 GHz至7.5 GHz的单边带外差锁定。环路带宽为400 MHz。(c)2012美国光学学会
A highly-integrated optical phase-locked loop with a phase/frequency detector and a single-sideband mixer (SSBM) has been proposed and demonstrated for the first time. A photonic integrated circuit (PIC) has been designed, fabricated and tested, together with an electronic IC (EIC). The PIC integrates a widely-tunable sampled-grating distributed-Bragg-reflector laser, an optical 90 degree hybrid and four high-speed photodetectors on the InGaAsP/InP platform. The EIC adds a single-sideband mixer, and a digital phase/frequency detector, to provide single-sideband heterodyne locking from -9 GHz to 7.5 GHz. The loop bandwith is 400 MHz.
