采用周跳判据，计算了光锁相环（OPLL）中激光器的最大线宽和环路增益随环路延迟和滤波器带宽的变化关系。结果表明，小于2 ns的环路延迟将允许使用最近报道的亚兆赫线宽单片可调谐半导体激光器的OPLL的实现。
Maximum laser linewidth and loop gain in an optical phase-locked loop (OPLL) are calculated as a function of loop delay and filter bandwidth, using a cycle-slipping criterion. It is shown that a loop delay of less than 2 ns would permit the realisation of OPLLs using the recently reported submegahertz linewidth monolithic tunable semiconductor lasers.
