Experimental demonstration of a 2-stage continuously tunable optical tapped-delay-line in which N+M pump lasers produce N×M taps

摘要

We experimentally demonstrate a 2-stage continuously tunable optical tapped-delay-line in which N+M pump lasers produce N×M number of taps. A 3×2-taps optical correlator is implemented to search multiple patterns among 20-Gbuad QPSK signals using nonlinearities and coherent comb source.
