Silicon photonics combined with complementary metal–oxide–semiconductor (CMOS) electronics leveraging wavelength-division multiplexing (WDM) are of interest for AI, optical computing, and high-speed Optical IO applications [1,2]. To power these applications, multi-wavelength light sources based on laser arrays [3] or mode locked lasers (MLL) have been proposed and demonstrated [4]. As optical sources mature, the CW-WDM multisource agreement (MSA) has emerged to define a set of wavelength grids and power levels so different applications can leverage a common set of laser technologies [5]. In this paper we demonstrate the first multi-wavelength optical source compliant with the CW-WDM MSA standard that operates from room temperatures through 100°C. The SuperNovaTM outputs 8 wavelengths across 8 fibers for a total of 64 optical carriers and complies with the 8+1 MSA wavelength plan (1 optional wavelength) with channels spaced at 400+/-100 GHz and output power within the Type 2 power class. The optical source is mode hop free with >40dB SMSR, <145 dB/Hz RIN, and <20 MHz linewidth across all channels and all operating conditions.
