Paper Abstract

An optical delay line rf filter using a 16-element laser diode array to tap an acousto-optic cell is demonstrated. The optical architecture uses heterodyne detection of multiple laser taps to sum delayed versions of an input RF signal. Experimental results are presented that verify performance as a variable delay line or RF filter. Application for the delay line filter includes analog signal processing in the RF or IF portion of a radar receiver.
