Multi-wavelength laser sources have gained significant interest for future high-bandwidth density DWDM optical links, enabling improved energy efficiency and bandwidth scaling. In this work, we present an integrated III-V/Si hybrid four-wavelength DFB laser with 200 GHz wavelength spacing and <10 dBm output power per wavelength. The wavelength spacing and total output power variations are <±25 GHz and <1 dB, respectively, for an ambient temperature change of 30°C. We also measured the relative intensity noise (RIN) and Lorentzian linewidth of the laser to be <-135 dB/Hz and <300 kHz, respectively.
