Paper Abstract

We have developed a novel opto-electronic transceiver designed to provide a jam-resistant, high-security, low- power rf communications link. By employing picosecond photoconductivity and a time-hopped spread-spectrum architecture, the transceiver can realize multi-octave instantaneous rf bandwidth. The design is capable of processing gains well above those of existing spread- spectrum communications systems. Hence, significant jam resistance is achievable with a minimum of rf power. The transceiver is particularly well suited to serve as the physical layer of a packet radio system and can be packaged in a hand-held unit with Q-switched diode laser technology. We present results from an opto-electronic digital spread- spectrum data link that demonstrate some of the capabilities of this approach.
