Optical techniques, devices and systems for combining duobinary modulation and optical subcarrier multiplexing in optical communication applications. An analog mixer is used to mix a duobinary signal for a data channel and a local oscillator signal to produce a modulation control signal for controlling the subsequent optical subcarrier multiplexing modulation. Various optical subcarrier multiplexing modulation techniques may be used including optical single sideband modulators and optical double sideband modulators.
