New inline wideband dynamic semiconductor laser amplifier model

Abstract

The formulation of a new scattering matrix, and the use of a gain compensation term allows the transmission-line laser model, previously described, to simulate both travelling-wave and Fabry-Perot laser amplifiers. The new model's results are in excellent agreement with those of other workers for both static operation of travelling-wave amplifiers and dynamic switching of Fabry-Perot amplifiers. To show the wideband nature of the model, a single-repeater 2 Gbit/s fibre communication system is investigated in both the time and frequency domains.
