Abstract
The electromagnetic characteristics of quantum-well structures with periodic dielectric perturbations are investigated numerically. The numerical solution of the differential equation is improved by using the implicit Range-Kutta method. By studying the mappings in the complex plane, the rule of choosing the sign of the transverse wave vector in the material with complex dielectric constant is established. In the discussion of the propagation characteristics, a comprehensive explanation of the resonance phenomena in periodic dielectric waveguides is presented. The main aim of the study is to determine grating strengths by analyzing the reflection and transmission characteristics of a quantum-well structure with a finite length grating. The power reflection and transmission are related to the grating strength in the various periodic dielectric waveguides.
