Driven primarily by cloud service and data-center applications, short-reach optical
communication has become a key market segment and growing research area in recent …

200-Gb/s per lane intensity-modulation (IM) direct-detection (DD) optics are being
commercialized to support 800G and 1.6 T applications inside datacenters. Though IM-DD …

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 …

Unlike ultralong coherent optical systems that seriously suffer from fiber nonlinearities, short-
reach noncoherent systems such as data center interconnections, which utilize small, cheap …

Vertical-cavity surface-emitting lasers (VCSELs) have made remarkable progress, are being
used across a wide range of consumer electronic applications, and have particularly …

The performance of high-speed intensity modulation direct detection (IM-DD) transmissions
is severely degraded by the linear inter-symbol interference (ISI), due to both bandwidth …

To meet rapidly growing customer-traffic demands, passive optical networks (PONs) have
been widely applied in optical access networks. However, one common imperfection of the …

Insufficient system bandwidth and chromatic dispersion (CD) of fiber are major limitations for
high-speed four-level pulse amplitude modulation (PAM4) direct detection systems. In this …

We investigate the modulational instability (MI) of a continuous wave (cw) under the
combined effects of higher-order dispersions, self steepening and self-frequency shift, cubic …

Metro network, as a medium distance transmission system, poses a special challenge of
transmission capacity and cost. In this paper, we present a detailed comparison of applying …
