1.52-1.59-μm range different-wavelength modulator-integrated DFB-LDs fabricated on a single wafer

We report for the first time different-wavelength modulator-integrated distributed-feedback laser diodes (DFB/MODs) fabricated on a single wafer, whose lasing wavelength cover almost all of the expanded erbium-doped fiber amplifier (EDFA) gain band from 1.527 to 1.593 /spl mu/m. The devices provided uniform and high-performance characteristics such as a… CONTINUE READING
