Abstract(in Japanese) (See Japanese page)
Abstract(in English) In this paper, we give for the frist time wide-angled finite-difference beam propagation algorithms based on a nonorthogonal coordinate transformation which extends the range of angled configurations for which beam propagation methods are accurate. This offers an extra degree of freedom within configuration and method applying wide-angle Beam propagation method in the design of general photonic integrated circuits incorporating angled waveguide sections. The present oblique beam propagation technique is compared with the conventional wide-angle BPM through numerical examples which are a tilted propagation in a dielectric waveguide and the diffraction of a focused gaussian beam in a homogeneous medium.
