DAC-free Ultra-Low-Power Dual-Polarization 64-QAM Transmission with InP IQ Segmented MZM Module

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate for the first time 32 GBd 64-QAM signal generation without the usage of DACs. The dual-polarization 64-QAM signal is transmitted error-free over 80 km of SSMF with 7.8 pJ/bit record low energy consumption.
