Abstract: Abstract We numerically propose a negative refractive index metamaterial structure with a unit cell composed of only one semi H-shaped element. With this structure a very high transmission of −0.65 dB and a low reflection of… read more here.

DOI: 10.1364/ol.480020
Abstract: An optical switch concept is presented which involves moving a negative-index metamaterial (NIM) load, possibly with loss, close to one waveguide in a two-waveguide directional coupler. The NIM load limits the number of optical modes… read more here.
