850 nm VCSEL and PD for Ultra High Speed Data Communication over Multimode Fiber

摘要

With the advent of cloud computing, the proliferation of smart phones and tablets, and the omnipresence of social networking, the bandwidth need for data communication continues its phenomenal growth. Less than two years after the high data rate of 14Gbit/s was finalized in 2011, the new high data rate of 25Gbit/s to 28Gbit/s is already upon us. In this paper, we report the development of the 850nm vertical-cavity surface-emitting laser (VCSEL) and photodiode (PD) at Sumitomo Electric Device Innovations USA (SEDU) to operate at this new data rate. These devices are targeted to use in active optical cables (AOC) and transceivers over multimode fiber for optical interconnect and short reach applications. We have successfully demonstrated their operation in an EDR AOC running at 25.8Gbit/s over 50 meters of OM3 fiber at Optical Fiber Communication Conference and Exposition (OFC) 2013.
