Abstract :
Using a single, dual-drive Mach-Zehnder modulator and high-speed electronics, differential quadrature phase-shift keying modulation and detection are demonstrated for a bit rate of 20 Gb/s. Back-to-back system performance is measured, and the receiver sensitivity is found to be -32.25 dBm.
