Demonstration of an LO-less, DSP-free QPSK Receiver for Data Center Interconnects
Rashmi Kamran, Nandakumar Nambath, Sarath Manikandan +4
We present the first demonstration of a local oscillator (LO)-less digital signal processing (DSP)-free coherent receiver for high-capacity short distance optical links. Experiment…
All-Analog Adaptive Equalizer for Coherent Data Center Interconnects
Nandakumar Nambath, Rakesh Ashok, Sarath Manikandan +5
In a high-speed coherent optical transmission system, typically the signals obtained at the receiver front-end are digitized using very high-speed ADCs and then processed in the di…
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…
