DAC-free Generation of M-QAM Signals with InP Segmented Mach-Zehnder Modulators

Not Accessible

Your library or personal account may give you access

Abstract

The concept of DAC-less generation of multi-level optical signals is discussed together with its latest InP-based results. A flexible transmitter sub-assembly enabling 32 GBd M-QAM operation up to 256-QAM is shown.
