A tunable leaky-mode reflection device operating in the visible region is introduced. This element

demonstrates ~100 nm tuning range with potential uses in tunable compact pixel structures for display

Design, fabrication and characterization of wideband guided-mode resonance polarizers with a single silicon layer are presented. The fabricated polarizer has an extinction ratio of ~670:1 at central wavelength λc = 1563 nm.

Leaky-mode resonance bandpass filters are designed with particle swarm optimization. The spectral phase properties of these elements are studied. It is shown that these elements can operate as optical delay lines.

A MEMS-tunable narrow bandpass filter concept is presented. This filter is based on the phase shift effect between two gratings resulting from halving a broadband high reflector guided-mode resonance structure.

Particle swarm optimization (PSO) is an evolutionary, easy-to-implement and promising technique to design optical diffraction gratings. In this paper, design of guided-mode resonance (GMR) grating filters using PSO is reported.

Examples of optical devices based on periodic leaky-mode resonant layers are presented. A single-layer element provides narrowband bandpass and bandstop filters and wideband reflectors and polarizers.

A periodic silicon membrane, designed by using the particle swarm optimization (PSO) technique, acts as a narrow bandpass leaky-mode resonance filter. The linewidth is ~0.5 nm at central wavelength of 1.55 μm.

Tunable leaky-mode resonant silicon-nitride pixels providing red/green/blue spectral lines are analyzed. Critical dimensions, rate of tuning, linewidths, and polarization properties are quantified.
