Abstract :
A new phase-shift keying configuration for a microwave optical link is presented. It is based on optical delay switching and consists of a light pulse source, a delay line, and a 2/spl times/1 light switch. A 2-Gb/s modulation at a carrier frequency of up to 40 GHz is made possible by using these fast optical devices.
