versatile digital GHz phase lock for external cavity diode lasers

WebWe propose a simple scheme to perform real-time and rapid measurements of the loop gain and bandwidth of a phase-locked loop (PLL) for mode-locked lasers. By implementing the proposed scheme, the loop gain and bandwidth of a laser-based PLL can be directly and accurately characterized in real time without breaking the original loop. WebWe propose a novel deep space optical communication scheme, in which an integrated optical phased array (OPA) is used for both phase modulation and ﬁne beam steering. In particular, an optical phase-locked loop (OPLL) based phased array with full electronic control over the phase is introduced and analyzed.
