摘要

考虑到二极管激光器前后面板之间的非线性半导体介质,基于Fox和Li型谐振腔进行了二极管激光器仿真计算。光场时间演化的跟踪被系统稳态的迭代逼近所取代。数值模型的基本方程是电场分布的亥姆霍兹方程和载流子扩散方程,外加复折射率和非线性增益函数。

Numerical simulations of new high-power, high-brightness diode laser structures
The diode laser simulation is based on a Fox and Li type resonator calculation taking into account the nonlinear semiconductor medium between rear and front facette of the diode laser. The tracing of the time evolution of the optical field is replaced by an iterative approximation of the steady state of the system. The fundamental equations of the numerical model are the Helmholtz equation for the electrical field distribution and the carrier diffusion equation, coupled by the complex index of refraction and the nonlinear gain function.
