Analysis of nonlinear pulse propagation and wave-mixing characteristics in SOAs
conference contribution
posted on 2021-04-19, 04:29 authored by Baji Babu Palagarla, Narottam DasNarottam Das, Mohammad RazaghiThis paper mainly focuses on nonlinear pulse
propagation and four-wave mixing (FWM) characteristics in
semiconductor optical amplifiers (SOAs). For simulation, modified
nonlinear Schrödinger equation (MNLSE) is used for the modelling
of pulse propagation in SOA. In this model, we have included the
gain dynamics and all nonlinear effects of the SOAs for simulation.
Finite-difference beam propagation method is adopted to solve the
MNLSE, obtained nonlinear pulse propagation and FWM
characteristics in SOA. The nonlinear pulse propagation
characteristics show that the output full width at half maximum
(FWHM) is linearly increases with increase of input FWHM. Output
pulse energy also increases with the increase of input pulse energy.
There are some dips occur at the output spectrum which is due to the
gain saturation and self-phase modulation (SPM) effects. The FWM
conversion efficiency is good if the detuning is <1 THz. Finally, the
FWM signal energy highly dependent on the input pump and probe
energies. The FWM signal peak power increases exponentially with
the increase of SOA length. Our simulation results are suitable for
the design of SOAs those are using in high-speed communication
systems and sensor network systems.
