Great stuff, thanks for pointing it out, Green88! Here are the relevant quotes from that recording:

6:29: "What's interesting about POET is – you know, beyond the electro-optical integration and the very high performance electrical or electronical that could be done – is that there is also a very significant capability to do optical processing, which means actually processing data in optical form."

8:35: "Sometimes with POET we won't have to convert optical signals to electrical and back. We can do significant processing in optical form."
