Three-Dimensional Metamaterials with an Ultrahigh Effective Refractive Index over a Broad Bandwidth
Three-Dimensional Metamaterial Ultrahigh Effective Refractive Index Broad Bandwidth
2015/8/10
The authors introduce a general mechanism, based on electrostatic and magnetostatic considerations,for designing three-dimensional isotropic metamaterials that possess an enhanced refractive index ove...
Time variation of refractive index in the core of active fiber under pulsed optical pumping
Time variation refractive index active fiber pulsed optical pumping
2015/8/4
The kinetics of refractive index change in active fiber under pulsed cladding-coupled optical pumping was investigated using interferometric technique. Relaxation processes after lasing threshold was ...
