Broadband Surface Plasmon Lasing in One-dimensional Metallic Gratings on Semiconductor

Abstract We report surface plasmon (SP) lasing in metal/semiconductor nanostructures, where one-dimensional periodic silver slit gratings are placed on top of an InGaAsP layer. The SP nature of the lasing is confirmed from the emission wavelength governed by the grating period, polarization analysis...
