High-symbol-rate coherentoptical transceivers suffer more from the critical responses of transceiver components at high frequency, especially when applying a higher order modulation format. We rece…
We report on a 16-nm CMOS DAC based transmitter optimization enabling bitrates up to 1.1 Tb/s. We describe the transmitter optimization and derive the maximization of the net bitrate. Based on back…
We report a new 128 GSa/s SiGe digital to analog converter (DAC) having 8 bit physical resolution and 24 GHz 3-dB bandwidth and present its architecture and the results on fundamental converter ass…
Intensity modulation with direct detection (IM/DD) provides a low-cost solution for data center optical interconnects. To achieve higher data rate, Tomlinson-Harashima precoding (THP) is adopted to…
