In this paper, we propose a reflectionless design of an optical waveguide coupler that is nonmagnetic and homogeneous. The coupler is designed using the linear coordinate transformation of triangles from virtual space to ...

In this paper, we introduce the generalized design of nonmagnetic homogeneous polarization splitting devices (polarization deflector/lateral shifter) based on linear area-preserving transformations for an arbitrary incident ...

Review of recent achievements in chalcogenide glass waveguide and fiber based all optical signal processing devices utilizing both short and long period gratings as well as the inherent ultra-fast, ultra-strong, third-order ...
