"The device was made in SFU's Compound Semiconductor Device Laboratory by a team led by Colombo Bolognesi and Simon Watkins. Its remarkable properties are made possible by the use of a new material system consisting of a very thin crystalline Gallium Arsenide Antimonide base and Indium Phosphide collector and emitter electrodes."

Dvorak, O. Pitts, S.P. Watkins and C.R. Bolognesi, Simon Fraser University, Burnaby, BC, Canada "We report highly manufacturable ultrahigh-speed NpN InP-based DHBTs with high-breakdown voltages based on the type-II band lineup at InP/GaAsSb heterojunctions. Manufacturability is enhanced by the simplicity of the DHBT layers, and device performance enables operation at >40 Gb/s with cutoff frequencies in excess of 250 GHz and BVceo > 6V." [Notice that the paper is only claiming "in excess of 250 GHz" but both the Georgia Straight http://www2.mybc.com/aroundtown/straight/ article that clued me to this and the Centre for Systems Science page at Simon Fraser University (http://www.sfu.ca/index4.htm) - where Bolognesi and Watkins do their research - claim 300 GHz.] Why is this significant? Bandwith on the Internet. These devices are lasers used to transmit signals down fibre optic pipes and are other semiconductor devices (hey, I don't understand it - I'm just trying to distill something in the popular press to a smaller format :-) ). The Georgia Straight (a publication in my area) article that clued me to this doesn't appear to be available online. If a fast typist on the list is willing to transcribe it, I will mail it to them. Please reply to my e-mail address, as I'm still on nomail. Marc^^^^^^**
