Using some theories and methods of semiconductor optical amplifier (SOA), vertical cavity semiconductor optical amplifier (VCSOA) and vertical cavity surface emitting laser (VCSEL), the multi-section model of LOA was built based on rate equations.

• 借鉴半导体光放大器(SOA)、垂直腔半导体光放大器(VCSOA)和垂直腔面发射激光器(VCSEL)的一些理论和方法,基于LOA的速率方程,建立了分段模型。
