Abstract
The emission of coherent light from a large area with a controlled directivity is required for high quality holographic system. In application domains like automotive, such a source needs to be fully planar for compactness and portability. It can be made of discretized sub-sources as long as they remain coherent and with the same directivity. We have considered here an array of connected waveguides covering the surface of a glass substrate. These waveguides spread the laser light out on the whole surface. Discretized plasmonic nanoantennas positioned at specific locations along the waveguides realise then the out-of-plane coherent beam steering.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
