We investigate narrowband transmission filters based on subwavelength-grating reflectors
at normal incidence. Computational results show that the filtering is realized through …

Monolayer two-dimensional materials (2DMs) have excellent optical and electrical
properties and show great application potential in photodetectors. However, the thickness at …

In this letter, a tunable and polarization-independent guided-mode resonance filter that has
two-dimensional crossed grating on a wedged waveguide layer of Ta 2 O 5 is fabricated and …

Spectral responses of the guided mode resonant filter under different planes of incidence
are comprehensively investigated in this paper. Commercially available software based on …

Narrowband filtering with high Q factors, polarization independency and tunability at high
THz frequencies is challenging. Here, combining guided mode resonance (GMR) and …

An angular-dependent polarization-insensitive filter in the telecommunication region is
demonstrated in this letter, which is based on a zero-contrast grating for incident plane …

The existing polarization-insensitive filters based on two dimensional (2-D) grating are
mostly under normal incidence. However, in filtering optical devices, the normal incidence …

To completely clarify the spectral responses of linear grating filters (LGFs) under full-conical
incidence (where the incident plane is parallel to the linear grating bars), a bandstop LGF is …

The results of full-scale experiments on models of a smart window with a double-grating
optical filter are presented. Such a filter has an angular-selective direct light transmission …

We design and implement one type of guided mode resonance (GMR) circular grating filters
(CGFs) on an HfO_2-on-silicon platform. Taking advantage of an angle-resolved micro …
