An Analog Signal Processing EIC-PIC Solution for Coherent Data Center Interconnects
Shivangi Chugh, Rakesh Ashok, Punit Jain +3
Data center interconnects (DCIs) will have to support throughputs of 400 Gbps or more per wavelength in the near future. To achieve such high data rates, coherent modulation and de…
An Endless Optical Phase Delay for Phase Synchronization in High-Capacity DCIs
Rakesh Ashok, Sana Naaz, Shalabh Gupta
In this work, we propose and demonstrate a module to linearly add an arbitrary amount of continuous (reset-free) phase delay to an optical signal. The proposed endless optical phas…
High-Capacity Coherent DCIs using PolMuxed Carrier and LO-Less Receiver
Rashmi Kamran, Shalabh Gupta
A PAM4 based direct detection system has been standardized for short-distance data center interconnects because of its simple architecture. Performance of the PAM4 systems is limit…
A Polarization Multiplexed Carrier based Coherent Link with Adaptive Polarization Control
Rashmi Kamran, Sana Naaz, Sarath Manikandan +3
Transmitting polarization multiplexed carrier makes the receiver of a coherent system local oscillator-less and frequency offset-free. A polarization multiplexed carrier based self…
