A compact indium phosphide (InP)-based integrated transmitter assembly consisting of a tunable laser and a double-nested Mach-Zehnder modulator (vector modulator) was successfully used for the generation of Nyquist-prefiltered quadrature phase shift keying (QPSK) and 16-ary quadrature amplitude modulation (16-QAM) signals at 32 Gbaud. With external polarization division multiplexing (PDM) emulation and digital coherent detection, we realized data rates of 128 Gb/s with PDM-QPSK and 256 Gb/s… CONTINUE READING
