Abstract

Embodiments of the present invention pertain to high-speed optical transmission and methods and apparatus to generate 16 quadrature amplitude modulated signals with simple and/or low cost architecture. More particularly, certain embodiments of the invention pertain to using parallel in-phase/quadrature modulators, driven by data signals and a clock signal, and curving the pulse by an intensity modulator. The 16 quadrature amplitude modulated optical signal may be detected, by a coherent detector, after transmission based on digital signal processing.
