Quasi-Optical Transceivers for Wireless Communications

Abstract

During the duration of this award we have demonstrated the following: (1) the first quasi-optical bidirectional amplifier array; (2) the array was used in a communication system and shown to have improved performance related to multipath fading due to built-in angle diversity; (3) the first quasi-optical isolator with no ferrite components, operating at X-band; (4) a two-stage quasi-optical lens amplifier array with improved feed efficiency and a cost of $85 /watt; (5) the first optically-controlled half-duplex T/R quasi-optical amplifier array with the possibility of extremely high-speed switching between transmit and receive functions. We also demonstrated a multi-user frequency reuse communication system based on the built-in angle-of arrival properties of lens amplifiers. 5 continued funded projects resulted from the accomplishments achieved under this award.
