64QAM Modulator With a Hybrid Configuration of Silica PLCs and LiNbO 3 Phase Modulators

Quadrature amplitude modulation (QAM) is a promising approach for increasing the spectral efficiency of wavelength-division-multiplexing transmission, but its optical implementation is challenging. We demonstrate a 64-level QAM (64QAM) modulator, which uses a signal synthesis in the optical domain....
