The results of that paper were obtained using experimental techniques that were primarily developed for the measurement of antenna-coupled detectors in the infrared. In the present paper, we show the results of spatial-response mapping obtained by using a dedicated measurement station for the characterization of optical antennas in the visible. At the same time, the bottleneck in the spatial responsivity calculation represented by the beam characterization has been approached from a different perspective. The proposed technique uses a collection of knife edge measurements in order to avoid the use of any model of the laser beam irradiance. By taking all this into account we present the spatial responsivity of optical antennas measured with high spatial resolution in the visible.engbook parthttp://dx.doi.org/10.1109/APS.2007.4396266http://cisne.sim.ucm.es/record=b3528557~S6*spirestricted access535621.396.67Optical antennasOptical detectionInfrared spectraLaser beamSpatial resolutionÓptica (Física)Óptica física, óptica cuántica2209.19 Óptica Física2209.19 Óptica física
