IQE demonstrates 40GB/s VCSEL technology for ne...

Cardiff, UK. 08 July 2010: IQE plc (AIM: IQE, "IQE" or the "Group"), the leading
global supplier of advanced semiconductor epitaxial wafer products and wafer
services to the semiconductor industry, has today published a joint paper in
Electronic Letters entitled "40 Gbit/s error-free operation of an oxide-confined
850nm Vertical Cavity Surface Emitting Laser (VCSEL)."

The paper reports on the significant demonstration of IQE's VCSEL materials
capability for high data transfer rate optical transmission required for
applications such as Active Optical Cables and Intel's LightPeak.

Existing copper interconnects between consumer devices such as BluRay DVD and
High Definition TVs are limited to data transfer rates of 0.48GB/s. Furthermore,
transmission distances for copper interconnects decrease significantly at higher
transmission rates.

The first generation of optical cables are designed to support data transfer
speeds of up to 10GB/s which is well within the 40GB/s demonstrated by IQE and
its partners in the European Union funded Vertically Integrated Systems for
Information Transfer (VISIT) programme.

The devices demonstrated in this project set a new world record for data
transmission at 850nm which is the standard wavelength used for peripheral and
LAN optical interconnects.

Mr. Andrew Joel, Product Director said:

"IQE has established a clear leadership position in VCSEL technology which has
uniquely positioned the group to exploit its expertise in the next generation of
high speed optical cables to meet the demands of ever increasing data transfer
rates for consumer, industrial, automotive and aerospace applications.

"High speed optical interconnects such as Intel's LightPeak are designed to
operate at twenty times the speed of today's copper technology and will be
scalable to 100GB/s in the coming years.

"In addition to the higher data speeds, optical connectors can be used over
significantly longer distances than would be possible with copper based cables."

Other members of the VISIT programme are Intel (Ireland), VI Systems (Germany),
Chalmers University of Technology (Sweden), The University of Cambridge (UK),
University College Cork (Ireland), The Technical University of Berlin (Germany)
and the Russian Academy of Sciences (Russia).

In July 2008 IQE's epiwafer material was used to demonstrate 25GB/s VCSEL
capability as part of the initial phase of the VISIT programme.
