Optical phase lock loop
Webterm phase coherence between these sources can be achieved using an optical phase-locked loop (OPLL). In such an OPLL, the rate at which the relative phase between a master laser and a slave laser changes is locked to a fixed value f beat called the beat frequency. A number of OPLL designs have been implemented [1–5]. WebOct 1, 2024 · Herein, we designed a multistage loop optical phase-locked system based on the Costas loop principle, which combines temperature tuning, piezoelectric (PZT) tuning, and acousto-optic frequency shifter (AOFS) tuning. It controls the local oscillator laser through the inner loop and outer ring, and completes the optical phase-locked function.
