1.1μm single mode VCSEL-based 4-channel × 10-Gbit/s parallel-optical module

For the first time, we fabricated a 1.1 μm InGaAs/GaAs single mode VCSEL-array-based 4-channel x 10-Gbit/s parallel-optical module integrated with a driver IC. The module achieved error free 10Gbit/s transmission for the distance of > 1km.
