Abstract

In this paper we investigate the homogeneous dielectric slab waveguide in the case of complex dielectric constants. A method for calculating the field distribution in a dielectric waveguide with an arbitrary symmetrical variation in the refractive index is developed, and some of the results are presented. The results are applied to the GaAs laser. It is fonud that the guiding mechanism is a combination of gain guiding and index antiguiding. Based on the calculations an explanation of the kinks on the light current characteristics is suggested.
复折射率介质平板波导应用于砷化镓激光器的理论
本文研究了复介电常数情况下的均匀介质平板波导。本文提出了一种计算具有任意对称折射率变化的介质波导中的场分布的方法,并给出了一些计算结果。结果应用于砷化镓激光器。结果表明,制导机构是增益制导和指数反制导相结合的。在计算的基础上,提出了对光电流特性的扭结的解释。
