Abstract

We devised a dual-carrier IQ modulator consisting of a novel complementary frequency shifter (CFS) and two IQ modulators. The CFS generates two optical subcarriers from a single light source and outputs them from separate ports without using any optical demultiplexing filters. We fabricated the modulator in a hybrid configuration of silica planar lightwave circuits and a LiNbO3 phase-modulator array. Frequency-spacing-tunable operation of the CFS was demonstrated. With the modulator, we successfully generated a 100-Gb/s/pol dual-carrier OFDM-QPSK signal.
