Numerical Study of the Small-Signal Modulation Bandwidth of Reflective and Traveling-Wave SOAs

IEEE/OSA Journal of Lightwave Technology
We present a comprehensive numerical model for intrinsic small-signal modulation response of both reflective, and traveling-wave semiconductor optical amplifiers. We investigate the small-signal photon and carrier density spatial distribution, modulation response, and -3 dB bandwidth for uniform and lossless traveling-wave modulation current model. The analysis shows that the current model does not significantly affect the modulation response as long as...

An analytical solution for stationary distribution of photon density in TW and RSOAs

Physica Scripta, IOP Publishing
In this paper, we analyze two semiconductor optical amplifier (SOA) structures, traveling-wave and reflective, with the active region made of the bulk material. The model is based on the stationary traveling-wave equations for forward and backward propagating photon densities of the signal and the amplified spontaneous emission, along with the stationary carrier rate equation. We start by introducing linear approximation of the carrier density spatial...

An Efficient Semi–Analytical Method for Modeling of Traveling–Wave and Reflective SOAs

IEEE/OSA Journal of Lightwave Technology
An efficient semi-analytical method is developed for fast and precise assessment of the steady-state gain characteristics of the semiconductor optical amplifiers. It relies on the analytical solution for the photon densities spatial distribution, starting with the rough estimation without the nonlinear gain suppression, and subsequent refinement of the results by inclusion of the suppression. Carrier density spatial distribution is approximated either by...

A Self-Consistent Numerical Method for Calculation of Steady-State Characteristics of TW and RSOAs

IEEE Journal of Selected Topics in Quantum Electronics
This paper presents a detailed numerical model of reflective and traveling-wave semiconductor optical amplifiers (SOAs), based on a self-consistent iteration method. The method is fully transparent to the input parameters and provides stable and efficient convergence of all relevant SOA variables as long as the sufficient number of previous iterations is taken into account. The model accounts for the detailed spectral and carrier density dependence of the...

Modelling of Carrier Dynamics in Multi-Quantum Well Semiconductor Optical Amplifiers

Physica Scripta, IOP Publishing
We present an analysis of carrier dynamics in a multi-quantum well (MQW) semiconductor optical amplifier in the saturation and recovery regimes. The model is based on an analytical solution of rate equations for carriers in the bulk and bound states of MQWs. The analysis shows that in the saturation regime, the carrier dynamics in the well, as well as material gain, considerably depends on the ratio of the differential gain to the nonlinear gain...

Application of Multi-Quantum Well RSOA in Remodulation of 100 Gb/s Downstream RZ Signal for...

19th Telecommunications forum TELFOR 2011
We investigate the possibility of remodulation of downstream 100 Gb/s signal into the upstream 10 Gb/s signal using multi-quantum well reflective semiconductor optical amplifier. Theoretical model used for analyzing carrier and photon dynamics in device takes into account forward and backward propagating amplified spontaneous emission noise. We present results for various downstream signal waveforms and different detector integrating times...
