1490 nm surface emitting DFB laser diodes operated by VCSEL driver ICs

Surface-emitting DFB lasers using a 45° total-internal-reflection facet mirror were optimized to feature extremely low threshold currents enabling deployment of commercial VCSEL drivers. The lasers incorporate a monitor photodiode that require no additional processing steps. An 8-array of such devices operated at 1.25 Gb/s showed a high degree of modulation uniformity and consumes only 1.4 W.
