Optical Phase-Conjugation of Picosecond Four-Wave Mixing Signals in SOAs

“…The FD-BPM (Conte & Boor, 1980;Chung & Dagli, 1990;Das et al, 2000;Razagi et al, 2009aRazagi et al, & 2009b is used for the simulation of several important characteristics, namely, (1) single pulse propagation in SOAs (Das et al, 2008;Razaghi et al, 2009aRazaghi et al, & 2009b, (2) two input pulses propagating in SOAs Connelly et al, 2008), (3) Optical DEMUX characteristics of multi-probe or pump input pulses based on FWM in SOAs , (4) , and (5) FWM conversion efficiency with optimum time-delays between the input pump and probe pulses (Das et al, 2007).…”

“…The FD-BPM is capable to simulate the optical pulse propagation taking into consideration the dynamic gain terms in SOAs (Das et al, & 2007Razaghi et al, 2009aRazaghi et al, & 2009bAghajanpour et al, 2009). We used the modified MNLSE for nonlinear optical pulse propagation in SOAs by the FD-BPM (Chung & Dagli, 1990;Conte & Boor, 1980).…”

“…In this chapter, we present the detail numerical simulation results of optical phase-conjugate characteristics of picosecond FWM signal pulses generated in SOAs using the FD-BMP (Das et al, 2000;Razaghi et al, 2009). These simulations are based on the nonlinear propagation equation considering the group velocity dispersion, self-phase modulation (SPM), and twophoton absorption (TPA), with the dependencies on the carrier depletion (CD), carrier heating (CH), spectral-hole burning (SHB), and their dispersions, including the recovery times in SOAs .…”

“…The FD-BPM (Conte & Boor, 1980;Chung & Dagli, 1990) is used for the simulation of several important charactreristics, namely, (1) single pulse propagation in SOAs (Das et al, 2008;Razaghi et al, 2009aRazaghi et al, & 2009b, (2) two input pulses propagating in SOAs (Das et al, 2000;;Connelly et al, 2008), (3) multiplexing of several input pulses using FWM , (4) two input pulses with phase-conjugation propagating along SOAs , and (5) two propagating input pulses with time-delay between them being optimized (Das et al, 2007).…”

“…The FD-BPM enables the simulation of optical pulse propagation taking into consideration the dynamic gain terms in SOAs (Das et al, 2007;Razaghi et al, 2009aRazaghi et al, & 2009bAghajanpour et al, 2009).
