Carrier lifetime variation and its effects on the chaotic behaviors in semiconductor laser
Abstract:Modeling theoretically the chaotic behaviors of semiconductor lasers, the carrier lifetime is usually treated as a constant (in this paper, it is called as the constant carrier lifetime assumption (CCLA)). In this paper, after considering the actually recombination mechanism of the carriers in the semiconductor, the variation of the carrier lifetime with the time has been obtained, and the chaotic characteristics of semiconductor laser with optical feedback have been investigated numerically. The obtained results have been compared with those obtained with CCLA, and the obvious differences can be observed.
