Ultra-Low-Power Single-Polarization QAM-16 Generation Without DAC Using a CMOS Photonics Based Segmented Modulator

Long-haul communication systems are requiring more and more spectral efficiency as data rates increase. QAM-16 is a promising candidate for each wavelength in a Wavelength-Division Multiplexed (WDM) system, providing double the spectral efficiency of Quadrature Phase-Shift Keying (QPSK) and four tim...
