Experimental demonstration of ultra-low-power single polarization 56 Gb/s QAM-16 generation without DAC using CMOS photonics

We experimentally demonstrate back-to-back transmission of QAM-16 at 56 Gb/s over a single polarization, representing a dual polarization system link of 112 Gb/s, without using an electrical DAC, on a CMOS Photonics platform.
