C-band tunable 6 mW vertical-cavity surface-emitting lasers

We demonstrate micro-electromechanical vertical-cavity surface-emitting lasers (MEM-VCSELs) that couple >6 mW of power into a single-mode fiber. These devices are continuously tunable across the entire c-band and offer error-free transmission over >500 km of single-mode fiber at OC-48 data rates.
