Error-free 46 Gbit/s operation of oxide-confined 980 nm VCSELs at 85°C

Abstract

A new design of oxide-confined 980 nm vertical-cavity surface-emitting lasers (VCSELs) particularly well-suited for very-short-reach (∼2 m and shorter) optical interconnects is presented. A new record for temperature-stable high bit rate VCSELs is achieved. Error-free data transmission at 46 Gbit/s is achieved up to a record-high temperature of 85°C. The maximum bit rate and -3 dB bandwidth at room temperature are 50 Gbit/s and 24.7 GHz, respectively.
