Particle swarm optimization (PSO) is an evolutionary, easy-to-implement technique to design optical diffraction gratings. Design of reflection and transmission guided-mode resonance (GMR) grating filters using PSO is ...

We introduce half-wave and quarter-wave retarders based on the dispersion properties of guided-mode resonance elements. We design the wave plates using numerical electromagnetic models joined with the particle swarm ...

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

We investigate the dispersion properties of leaky-mode

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.

A dielectric grating on a metallic substrate permits excitation of both surface-plasmon polaritons (SPPs) and resonant leaky-modes. We compare the spectral characteristics and local field structure of the excited classical ...

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.
