Modal Analysis for Single-Mode Waveguides of Silicon on Sapphire (SOS) at Infrared Region Using Finite Element Method (FEM) [PDF]
Journal of Applied Sciences and Nanotechnology, 2022 One of the recommended platforms for waveguide generation in the infrared region is silicon-on-sapphire (SOS). This paper proposes a modal of the optical waveguide of silicon on a sapphire from ), using FEM (finite-element method) solver simulation ...

Quantum Electrodynamics in a Topological Waveguide [PDF]
Physical Review X, 2020 While designing the energy-momentum relation of photons is key to many linear, non-linear, and quantum optical phenomena, a new set of light-matter properties may be realized by employing the topology of the photonic bath itself.
