Abstract
We report for the first time different-wavelength distributed-feedback laser diodes (DFB-LDs) fabricated on a single wafer, whose lasing wavelengths cover the expanded erbium-doped fiber amplifier (EDFA) gain band from 1.52 to 1.59 /spl mu/m with adjusted detuning between lasing-wavelengths and gain-peak-wavelengths. Uniform lasing characteristics such as a low-threshold current of less than 12 mA with stable single-mode oscillation of more than 35-dB side-mode suppression ratio (SMSR) are achieved for the 75-nm wavelength range.Keywords
