Abstract :
We review recent advances in the pursuit of photon-efficient modulation and detection for optical communications. Hybrid modulation superimposing coherent modulation on pulse-position-modulation and 4-dimensional modulation are presented. Applications of these high photon-efficiency formats are discussed.
