Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes ...

Abstract: In this work, we investigate the performance of geometric constellation shaping for highorder coded quadrature amplitude modulation (QAM) over an additive white Gaussian noise (AWGN) channel ...

Abstract: The increasing demand for data throughput in modern data centers has intensified the need for high-speed, energy-efficient optical interconnects. Although traditional intensity-modulation ...
