High-speed free-space based reconfigurable card-to-card optical interconnects with broadcast capability

Abstract

In this paper, we propose and experimentally demonstrate a freespace based high-speed reconfigurable card-to-card optical interconnect architecture with broadcast capability, which is required for control functionalities and efficient parallel computing applications. Experimental results show that 10 Gb/s data can be broadcast to all receiving channels for up to 30 cm with a worst-case receiver sensitivity better than ?12.20 dBm. In addition, arbitrary multicasting with the same architecture is also investigated. 10 Gb/s reconfigurable point-to-point link and multicast channels are simultaneously demonstrated with a measured receiver sensitivity power penalty of ∼1.3 dB due to crosstalk. © 2..
