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.

We have demonstrated 7 dB of C-band amplification from a DRA; pumped using novel incoherent high-power (>450 mW) semiconductor sources with a broad spectral bandwidth (>35 nm). The low-frequency RIN of these sources can be suppressed below -140 dB/Hz.
