We provide on overview of fundamental technologies and recent challenges on extremely higher-order quadrature amplitude modulation (QAM) such as 256–1024 levels, toward the realization of an ultrahigh spectral efficiency approaching the Shannon limit. Key components required for such a higher-order QAM transmission are described in detail, including a coherent light source, an optical phase-locked loop, an IQ modulator, and a digital demodulator. We also present re...

Extremely Higher-Order Modulation Formats (Optics and Photonics) | Masataka Nakazawa, Toshihiko Hirooka, Masato Yoshida, Keisuke Kasai. Which are the reasons I like to read books. Great story by a great author.
