Abstract
An inventive transceiver includes a transmitter for outputting plural beams of electromagnetic energy. In the illustrative embodiment, the transmitter is a vertical cavity surface emitting laser. Plural beams output by the transmitter are directed to the detector by an array of diffractive optical elements. In the preferred embodiment, the optical elements are fabricated by imprinting a pattern on a high temperature film substrate using an ultraviolet epoxy. The use of a vertical cavity surface emitting laser allows for high data rates while the diffractive optical arrangement allows for a compact design.
