Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

Smart, low-cost and portable gas sensors are highly desired due to the importance of air
quality monitoring for environmental and defense-related applications. Traditionally …

Due to their transparency and tunable electrical, optical, and magnetic properties, metal
oxide thin films and structures have many applications in electro‐optical devices. In recent …

We experimentally and theoretically demonstrate a class of narrowband transmissive filters
in the terahertz spectrum. Their operation is based on the excitation of guided-mode …

This paper presents a fully analytical model to determine the transmission and reflection
properties of planar 1-D distributions of metal strips or slits made in thin metal screens. In …

Plasmonic spectrum filtering devices based on metallic nanostructures have attracted wide
attention due to their good reliability, ease of fabrication, and wideband tunability. However …

We present a high-index contrast dielectric grating design for polarization-independent
narrowband transmission filtering. A reduced symmetry hexagonal lattice allows coupling to …

The design of photonic structures plays a crucial role in the engineering of light-matter
interactions. Planar microcavities have been widely used to establish strong light-matter …

We propose a six-layer waveguide structure embedded in a single-layer grating based on
guided-mode resonance (GMR), which can realize ultra-narrowband filtering with a tunable …

The spectral response of a terahertz (THz) filter is investigated in detail for different angles of
incidence and polarization of the incoming THz wave. The filter is fabricated by patterning an …
