SPM Response of a Distributed coupling coefficient DFB-SOA All-Optical Flip-Flop
Authors
Abstract
Deriving a dynamic model based on the coupled-mode and carrier rate equations, the effects of coupling coefficient and corrugation position on all-optical flip-flops (AOFF) we have analyzed in this paper. Also the self phasemodulation (SPM) in the distributed coupling coefficient distributed feedback semiconductor optical amplifier (DCCDFB- SOA) has been implemented. Then the effects of SPM on the rise and fall times of the flip-flop DFB-SOA are investigated. It has been shown that the application of the optimized coupling coefficient and corrugation position improves the speed limitation in AOFF significantly. The transfer matrix method (TMM) time domain is utilized for the numerical simulations.
