not mention of POET and no link... just interesting and here is an abstract

“The key to this is that optical engine,” he said, “which has a couple of components on it. It has the host electrical interface that receives a short reach electrical interface from the GPU. It has modulator drivers to modulate the ring resonators as well as control circuitry, for example, to maintain the temperature of the ring resonators [which must be at] a very accurate temperature to keep the frequency stable. It then has waveguides to grating couplers that couple that energy into the fiber that goes to the switch.”

Also, just some other interesting read about Go Fotonix from GF.
