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 ...

K310 is a cold-work tool steel used in manufacturing of forging dies. To study hot deformation behavior and flow stress model of the steel, continuous hot compression tests in the range of 900-1100ºC with strain rates of 0.01,0.1 and 1s-1 were...

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

systems.

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.
