Abstract

We report the demonstration of a 4-bit optoelectronic-switched silica- waveguide time-delay network. Targeted for insertion into a 96-element L-band conformal array, the optical time-shifter provides 16 programmable time-delays in steps of 0.248 nsec. By characterizing its RF insertion phaser and synthesized pulse response, we verified that the relative time-delays generated by the waveguides were within 15 psec of their designed value.
