We report the first bulk metamaterials at visible frequencies that shows intriguing negative refraction for all incident angles. The metamaterial is realized by growing silver nanowire in a porous alumina template.
We present the formulation of wave propagation in arrays of subwavelength waveguides with sharp index contrasts. We demonstrate the collapse of the bands into evanescent modes, and propagation of lattice solitons with superluminal phase velocity.
We show that two Bloch modes launched into a nonlinear photonic lattice can evolve into a supercontinuum of spatial frequencies, exhibiting a sensitive dependence on the momentum difference of the two initially excited modes.
Fast wavelength selective switching implemented by an electroholographic switch constructed of a KLTN:Cu crystal is presented. Switching at 7 nanoseconds and selectivity of 100GHz were obtained.
