We review coded modulation for next-generation coherent optical communications systems. Geometric constellation shaping is discussed in detail, along with strategies to maintain complexity at levels comparable to a conventional square quadrature amplitude modulation (QAM) with bit-interleaved coded modulation (BICM) architecture.
