“The ability for POET to passively attach high power CW 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.”
