Accurate self-orientation within a space can be achieved using only a simple photodetector and a remote Gallium Nitride micro-light-emitting diode array, emitting a time series of varying spatial illumination patterns onto the scene.
We discuss the development of silicon photonic microring resonators for the emission of optical vortex beams. These devices offer great potential for high capacity short-reach optical interconnects thanks to their compactness, low power consumption and fast reconfigurability.
