Abstract
The perfect matched layer (PML) backed by infinite potential barriers is applied to state analysis of tilted quantum well structure where electron wave can be represented by quasi-bound state. Electroabsorption with exciton effect in quantum well is calculated based on quasi bound state. In comparison with commonly used infinite potential barrier boundary, PML allows the analysis of the structures under strong applied electrical field and/or shallow quantum well which can find applications in electro-absorption based devices such as modulators and wavelength converters.
