In this paper, a tunable, two-dimensional periodic structure based on guided-mode resonance (GMR) is proposed. This element can be employed as a tunable optical filter or a display pixel. Resonance tuning in this device ...

In this paper, a novel tunable DGS filter is proposed to provide a frequency-rejection property at centre frequency of 2.4 GHz. The new structure has a simple and compact shape and its rejection characteristic is sharp at ...

Widely tunable display pixels are reported. The pixel consists of

a subwavelength silicon-nitride/air membrane containing complementary

fixed and mobile gratings. By altering the device refractive index ...
