Definetely good news is that the PET does also include some optics: "Devices include complementary HFET and HBT transistors with high electron mobility performance, including a thyristor with both optical and electrical operation."

And really thrilling is that they are aiming at 40 nm: "We are delighted to target a 40-nm technology node for our first PDK delivery. This is an aggressive target for our POET devices and process IP. This will demonstrate to the industry the significance and the strengths of POET compared to the performance and power efficiency of today's widely used technologies." (Copetti)
