I suppose the question is.  How do Ayar labs use these DFB lasers in the SuperNova lightsource?  Presumably they aren't using a flip-chip onto a OI process like POETs LightBar does.  Remember the OI allows for active and passive optical components to be intergated into a complete light source, such as StarLight. This does away with the costly active alignment of the lasers arrays.  This appears to be 75% lower in cost for CAI.  

“We are delighted to continue to work with Celestial AI to provide a high-volume manufacturable solution for their optical interconnect technology platform,” he adds. “The ability for POET to passively attach high-power CW [continuous wave] lasers on its optical interposer at wafer scale enables the use of single known-good laser chips and eliminates the need for laser arrays, which can be cost prohibitive for high-volume applications. The POET team has worked closely with Celestial AI to define a low-cost packaging solution that is up to 75% lower in cost than competing solutions and is highly scalable for the volumes that Celestial AI is projecting.”
