Nonlinear Models of Traveling-Wave Optical Amplifiers.
01 January 1989
The nonlinear phenomenon in semiconductor traveling-wave optical amplifiers has thus far been studied using a pair of coupled partial differential equations, the wave equation and the rate equation. Simple, small- and large-signal nonlinear models of such amplifiers are presented, which, though obtained from the above equations, are nmuch more suitable for computing the output response associated with arbitrary input signals.
