Title: Chaotic dynamics of an optical phase locked loop having loop filter with high frequency gain
Abstract: Nonlinear dynamics of optical phase locked loop (OPLL) in presence of loop delay, considering proportional plus integrating type loop filter (LF) has been studied. Analytical and numerical results show that with proper choice of frequency gain, chaos generated in the system due to loop delay can be suppressed. Also the loop performance can be improved, so that the loop can operate in stable locking condition for some higher values of additional loop delay compared to the loop with imperfect integrating type LF. From analytical results, it is possible to choose a suitable value of the high frequency gain and other system parameters for controlling nonlinear dynamics of the loop. Analytical predictions have been verified by solving the system equations numerically.
