Transmission resonances in silicon subwavelength grating slot waveguide with functional host material for sensing applications

Optics and Laser Technology, 2021
A highly sensitive and selective CO2 gas sensor is presented based on a subwavelength grating (SWG) slot waveguide. Polyhexamethylene biguanide (PHMB) as a functional material fills the slot gap as well as the space between the silicon pillars of the SWG

Efficient light coupling between dielectric slot waveguide and plasmonic slot waveguide

Optics Letters, 2010
An efficient coupler between a dielectric waveguide and a plasmonic metal-insulator-metal (MIM) waveguide is proposed, modeled, fabricated, and characterized. Based on the platform of a silicon slot waveguide, a quasi-MIM plasmonic junction is formed via e-beam lithography and lift-off process. Coupling efficiency between the silicon slot waveguide and

Strip-loaded horizontal slot waveguide

Optics Letters, 2017
We introduce a novel concept for an optical waveguide called a strip-loaded slot waveguide. It allows an extraordinary confinement of the field in a waveguide with an extremely tiny (vertical) cross section. Unlike conventional slot waveguides, the proposed configuration has potential for very low propagation losses.

Directivity‐enhanced planar slot antenna backed by substrate integrated waveguide cavity

Microwave and optical technology letters (Print), 2023
In this paper, a directivity‐enhanced planar slot antenna (PSA) backed by substrate integrated waveguide (SIW) cavity is proposed to solve the problem of maximum gain direction bias.
