Abstract We propose a polarization-insensitive design of a hybrid plasmonic waveguide (HPWG) optimized at the 3.392 µm wavelength which corresponds to the absorption line of methane gas. The waveguide design is capable of providing high mode sensiti

We design and optimize an optical coupling structure between a superluminescent light emitting diodes (SLED) and SiNx waveguides for the optical sensing, in which an efficient coupling between these waveguides is challenging due to significant cross-

The design and modeling of a highly sensitive sensor based on a slot photonic crystal waveguide (slot-PCWG) is presented. The structure consists of cylindrical air rods drilled in a dielectric slab on a triangular lattice, which are filled with SiO2.
