Abstract :
A 3-bit fibre-optic delay network with linear differential insertion phase from 1 to 11 GHz was demonstrated. Discrete delay increments specified by the steering angle of the phased array antenna were implemented by switching the bias currents of high-speed 1.3 mu m laser diodes pigtailed to the delay lines.
