Design, Analysis and Experimental Testing of BPSK Homodyne Receivers Based on Subcarrier Optical Phase-Locked Loop

Abstract

The analysis of a subcarrier optical phase-locked loop (SC-OPLL) is carried out in order to optimize phase-locking performance. A new parameters optimization procedure, useful for OPLL design, is demonstrated theoretically and experimentally. An SC-OPLL based on this procedure has been realized, so a pilot carrier SC-OPLL and a nonlinear SC-OPLL optical receiver have been experimentally constructed and tested. An 8B/10B line coding is employed for pilot carrier SC-OPLL receiver in order to improve performance and a new architecture of decision-driven PLL is experimentally demonstrated.

Nonlinear dynamics of an optical phase locked loop in presence of additional loop time delay

“…(8) is solved by numerical integration technique according to 4th order Runge-Kutta algorithm for different values of system parameters and time delay. In the numerical simulation, [7,11]. From Fig.…”

“…With the advancement of optoelectronic technology, PLL systems have been designed in the optical frequency range also [7]. As such OPLLs have huge application potential and several works on OPLLs have been reported in the literature [8][9][10].…”
