pmud> uninformed as to who, what, why PET is and what is the tie-in with POET.

in a nutshell, PET is the electronic subset of POET.

same manufacturing advantages, for use-cases that don't have optical elements.

to inform thyself, see the corporate presentation deck on the company website, or their news releases, such as:

PET Advances

Specific TCAD efforts are focused on complementary hetero-structure field-effect transistors (HFETs) and bipolar transistors (HBTs), which form the basis for the first TDK release focused on the planar electronic technology (PET), the electrical subset of the POET process. It can support complementary HFET (CHFET), bi-CHFET, bipolar and thyristor device fabrication. PET offers lower cost and simpler process fab options for applications that do not require the full optical feature set offered by POET.

All of the electronic devices of the PET platform represent a breakthrough in performance and power efficiency over existing silicon CMOS technologies that exist today and on the industry roadmap.

By enabling increased speed, density, reliability, power efficiency, and much lower bill-of-materials and assembly costs, the POET semiconductor platform provides disruptive performance with an industry-compatible transition framework, and positions the Company as a leader in the new generation of companies defining the growth paradigm in the post-Moore’s Law world.
