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…

Adaptive Polarization Control for Coherent Optical Links with Polarization Multiplexed Carrier
Mehul Anghan, Nandkumar Nambath, Rashmi Kamran +1
Self-homodyne systems with polarization multiplexed carrier offer an LO-less coherent receiver with simplified signal processing requirement that can be a good candidate for high-s…
