The tremendous growth of data traffic has spurred a rapid evolution of optical
communications for a higher data transmission capacity. Next-generation fiber-optic …

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 …

Global data traffic is growing rapidly, and the demand for optoelectronic transceivers applied
in data centers (DCs) is also increasing correspondingly. In this review, we first briefly …

We report compact, scalable, high-performance, waveguide integrated graphene-based
photodetectors (GPDs) for telecom and datacom applications, not affected by dark current …

Conventional electronic and photonic devices are inherently 2D and rigid because of the
substrates on which they are fabricated. However, the world is not flat and stiff: There are …

Optical communication systems, operating in C-band, are reaching their theoretically
achievable capacity limits. An attractive and economically viable solution to satisfy the future …

A tunable metamaterial (MM)-based silicon (Si) waveguide is presented that is composed of
an MM nanodisk array on a Si-on insulator substrate. A significant modulation efficiency of …

An ultra-sharp multimode waveguide bend (MWB) based on a multimode waveguide corner-
bend (MWCB) is proposed and realized. With the present MWCB, total internal reflection …

We introduce PULSE, a sub-s optical circuit switched data centre network architecture
controlled by distributed hardware schedulers. PULSE is a flat architecture that uses parallel …

In this paper, we present Alibaba's practices and views on open and disaggregated optical
transport networks, with a focus on metro data center interconnects (DCIs). We first discuss …
