200 Gbps/Lane IM/DD Technologies for Short Reach Optical Interconnects [PDF]
Journal of Lightwave Technology, 2020 Client-side optics are facing an ever-increasing upgrading pace, driven by upcoming 5G related services and datacenter applications. The demand for a single lane data rate is soon approaching 200 Gbps. To meet such high-speed requirements, all segments of traditional intensity modulation direct detection (IM/DD) technologies are being challenged.

Hard-Decision Coded Modulation for High-Throughput Short-Reach Optical Interconnect [PDF]
Entropy, 2020 Coded modulation (CM), a combination of forward error correction (FEC) and high order modulation formats, has become a key part of modern optical communication systems. Designing CM schemes with strict complexity requirements for optical communications (e.g., data center interconnects) is still challenging mainly because of the expected low latency ...

IEEE Open Journal of the Solid-State Circuits Society, 2022 This paper describes the energy-efficient realization of a QPSK optical receiver (CoRX) for short-reach intra-datacenter interconnects based on analog coherent detection. The CoRX comprises inphase and quadrature channels for each polarization and a high-

A Cost-Effective 2-Channel OTDM System Implemented With Sinusoidally Modulated Light Source
IEEE Access, 2020 We propose to implement a 2-channel optical-time-division-multiplexed (OTDM) system for short-reach optical interconnects by using a sinusoidally modulated light source instead of a complicated mode-locked laser as an input pulse source.
