Abstract :
We devised a dual-carrier QPSK modulator that uses both analogue electrical and optical modulation, which simplifies the optical circuit configuration and reduces the power consumption of a transmitter. We demonstrated the generation of dual-carrier 14-Gbaud QPSK signals with the devised modulator.
