CW-WDM MSA compatible 100-mW (up to 50°C), 400-GHz spacing highly-reliable CW-DFB 8-channel laser array

We demonstrate a CW-WDM MSA compatible 8-channel 400-GHz spacing 100-mW CW-DFB laser array, with uniform channel spacings (±100 GHz) from 20 to 75°C, small channel-to-channel power deviations (0.56 dB) and over 2000-hour-operation reliability at 80°C.
