This work overcomes the difficulty of the previous matched interface and boundary (MIB)
method in dealing with interfaces with non-constant curvatures for optical waveguide …

For optical waveguides with high index-contrast and sharp corners, existing full-vectorial
mode solvers including those based on boundary integral equations typically have only …

For optical waveguides with high index contrast and sharp corners, high order full-vectorial
mode solvers are difficult to develop, due to the field singularities at the corners. A recently …

This paper presents a new full-vectorial higher order finite-difference scheme for rectangular
dielectric waveguides. The method incorporates new difference equations for mesh points …

In this work, a computationally fast, numerically stable, and memory-efficient cascading and
doubling algorithm is proposed within the method of lines framework to model long planar …

This paper introduces the matched interface and boundary (MIB) method for the eigenmode
analysis of two dimensional step-index waveguides. The MIB method distinguishes itself …

The main purpose of this study is designing a structure with the broadband negative
refractive index (NRI) in the wavelengths range of 3-5 μm using multilayer structures. In the …

The polarizers are important elements of integrated optical circuits. In this research work, two
types of metal-clad TM-pass polarizers, transmission mode polarizer and reflection mode …

A compact 90° three-branch beam splitter is proposed. The device relies on the use of a
high contrast material system. It utilizes a rectangular resonant cavity for its operation, which …

A finite difference scheme with a uniform mesh for planar waveguides with arbitrary
refractive index profiles that takes full account of any smooth index variation and index …
