Paper Abstract

Most of optoelectronic semiconductor devices, especially quantum well based ones, make use of a grating to couple the active layer to free space. To go beyond the simplistic coupling role of the grating we propose a specifically designed metal-dielectric corrugated interface that squeezes normal incidence light in subwalength scale, taking advantage of the very active work achieved over the last few years in near field electromagnetism. This structure coherently combines three surface plasmon engineering tools: Bragg reflection, microcavity, and grating coupling. These electromagnetic properties are demonstrated experimentally in the gigahertz regime, as a function of design parameters. Light squeezing is observed down to a quarter of a wavelength.
