This work presents the design and multiphysics simulation of a cylindrical waveguide-based optical switch using germanium-antimony-tellurium (GST) as an active phase change material. The innovative ...
Geometrical optics (GO) and physical optics (PO), supplemented with geometrical theory of diffraction (GTD) and the uniform theory of diffraction (UTD) and the Huygens-Fresnel principle are usually ...
