Abstract

We designed a programmable delay line using laser diodes to tap an acousto-optic cell. The laser diodes optically tap the Bragg cell at varying distances from the transducer to create delayed versions of the input signal. We describe the optical architecture that uses heterodyne detection to collect delayed versions of the input signal. We present experimental results that verify system performance. Applications for the delay line include radar and signal processing systems.
