To reveal origins of resonance characteristics of multilayer interference structures, we
developed an ab initio spatial coupled-mode theory using the approximations of general …

We establish the connection between two theoretical approaches widely used for describing
resonant optical properties of guided-mode resonant gratings (GMRGs): the coupled plane …

In this paper, we have theoretically studied transformations of higher-order modes and
angular momentum of light in the optical snake, a coil resonator composed of two …

We examine the use of foundry process optical waveguide couplers in making 1× 2 optical
switches. The concept involves a post-foundry process to provide a moveable dielectric load …

In this paper, a three ringresonator serially coupled is considered as an optical filter. We are
going to improve the performance of the designed optical filter by increasing the quality …

Abstract Ultra-broadband (dc-to-millimeter-wave or dc-to-terahertz) electromagnetic signals
are instrumental for many applications such as imaging, sensing, security scanning, high …
