Frequency-domain model of multiwave mixing in bulk semiconductor optical amplifiers

Abstract

We present a new steady-state frequency-domain model of highly nondegenerate four-wave mixing in bulk semiconductor optical amplifiers (SOA's). The model can handle a large number of interacting optical fields and situations in which the nonlinear interactions are complex. It accounts for the longitudinal dependence of the population inversion in the SOA and the spectral dependence of the gain. Carrier population pulsations, spectral-hole burning, and carrier heating, which dominate the nonlinear response over bandwidths into the terahertz range, are included. The model also includes output amplified spontaneous emission noise and allows important system parameters such as signal-to-noise ratio and noise figure to be estimated. A number of applications of the model are presented in which good agreement between theoretical and experimental results is demonstrated.Index Terms-Four-wave mixing, optical frequency conversion, semiconductor device modeling, semiconductor optical amplifiers, wavelength division multiplexing.

All-optical Read Only Memory Employing SOAs

“…In our numerical assessment, the propagation equation and the rate equation were adopted from reference [7] to create Equations (3) and (4). To make faster calculations, the integral equation approach [8] was used for the static simulation by modifying Equation (3), so the equation takes the integral form as shown in Equation (5).…”

“…To study the cross-gain modulation (XGM) characteristics of the SOA, steady-state numerical analysis was carried out utilizing the multi-wavelength propagation equation (3) and the rate equation (4) (Summerfield and Tucker 1999). It is worth to note that, integral equation approach (Eq.…”

“…The NL interaction of four equally spaced channels (signals) that are injected into an SOA has been previously investigated, especially in connection to the wave-mixing problem (Summerfield and Tucker 1999). Research interest on this topic peaked in the late 80s (Inoue 1987(Inoue , 1989Yu 1989) and then petered out with the appearance of EDFAs.…”
