Abstract
Embodiments for improving the Signal to Noise and Distortion (SINAD) ratio in Pulse Amplitude Modulation (PAM)-M optical intensity modulation systems, to enable higher data rate communications, are provided. Embodiments can be used to improve the linearity and reduce the distortion of electrical and electro-optics components (including optical modulators) in optical intensity modulation systems. Embodiments are well suited for use with PAM-M optical intensity modulators, such as segmented Vertical Cavity Surface Emitting Laser (WSEL) and segmented Mach-Zehnder Modulator (MZM), for example.
