25 Gb/s at 200 mW via 19-Element 980 nm VCSEL Arrays

Novemdecuple (19-element) electrically parallel, optically uncoupled vertical cavity surface emitting laser arrays exhibit 18 GHz bandwidth, transmit pseudorandom digital data at 25 Gb/s with a bit error ratio of 1 × 10
^-13
, and emit up to 200 mW at 980 nm.
