Abstract
A holographic element (HOE) with multiple apertures formed in a single substrate for use an optical communication system. The multi-aperture HOE can be use instead of an optics unit having one or more separate optical elements for each aperture needed by an optical transmitter, receiver or transceiver. The single substrate reduces complexity and cost relative to conventional system that the use separate optical elements to implement the optics unit.
