Abstract

This paper analysis the spectral characteristics of optical pulse amplifications in semiconductor optical amplifiers under transparent assist light injection, comparison with the gain region light injection is also been given. It is shown that gain region light can decrease the spectral broadening and shifting, while transparent light can’t improve the spectral distortion though it can accelerate the carrier recovery. The effect of the assist light’s power, shape and initial frequency chirp of the input pulses on the shape and the spectrum of the amplified pulse are discussed in detail. The relationship of the maximum spectral shifting with the amplifier’s length, bias current is also been given, particular attention is paid to the difference in co- and counter-propagating assist light injection.
