High-speed card-to-card optical interconnects are highly demanded in high-performance computing and data centers. Compared with other solutions, free-space optical interconnects have the capability of providing both reconfigurability and flexibility. In this paper we propose and experimentally demonstrate a free-space based reconfigurable optical interconnect architecture and it is capable of connecting cards located both inside the same rack as well as in different racks. Results show that 3×10 Gb/s data transmission is achieved with a worst-case receiver sensitivity better than -9.38 dBm.
In this paper a novel high bandwidth optical wireless communication system for indoor personal area networking
applications with both ubiquitous coverage and mobility feature is proposed and tradeoffs are studied. Gigabit-per-second
optical wireless communication system with limited mobility provided to users has been demonstrated by proof-of-
concept experiments for the first time. It has also been shown that when incorporating with the WiFi-based
localization system, our proposed system can provide high-speed error-free operation with mobility over the entire room.
