ACP-OPLL Performance in Presence of Out-of-Band Interference

Nonlinear dynamics inside an optical phase locked loop (OPLL) were studied to determine their effect on the OPLL performance in radar front end applications. An improved theoretical model of the OPLL was presented. Numeric simulations were performed to study the OPLL performance penalties in presence of external interference and its dynamic behavior during phase tracking failure. These results were validated by experimental observations.
