Some clarifications:

Our current VCSEL milestone operates @ 50GHz in a dense wavelength division mutiplexing format(vs. single fiber mode) in the 850nm wavelenght.

It's important to regonize the difference between PET & POET, if you don't, please look it up(PET-Electrical/POET-Optical).

We're working on a 40nm PTK for PET (it has no connection to the 50GHz VCSEL at 50nm)

"PET Foundation PDK (Process Design Kit) targeting 40nm (V 1.0) Design rules and parameters library models for PET process. Devices include complementary HFET and HBT transistor and a thyristor with both optical and electrical operation."

PET lays the foundation for POET.

New in latest MD&A:

"Demonstration of a switching VCSEL – which is a key optical engine in the creation of single chip opto-electronic transceivers and changes the current paradigm of analog lasers and detectors."


In the C.V. Yao is saying they've achieved a VCSEL @ 980nm wavelenght at a 50nm integration in a POET format. NOT a "40nm PET".
