摘要

We demonstrate a four-wavelength DFB laser with 140 GHz wavelength spacing, 8.0 dBm/wavelength output power, <-140 dB/Hz RIN, and <300 kHz linewidth. We achieved >13 dBm/wavelength fiber coupled power with an amplifier. The wavelength spacing and power variations are <±5 GHz and <±0.8 dB, respectively.
