IQE plc : IQE's VCSEL products achieve key milestones in high volume photonic communications applications
(Thomson Reuters ONE) -
Cardiff, UK. 23 May 2013: IQE plc (AIM: IQE; "IQE", "the Group") announces that
vertical cavity surface emitting laser (VCSEL) devices using wafers produced at
its Cardiff, UK facility have broken the 40 Gbit/s barrier at high temperatures.
This is a key milestone in the adoption of photonic technologies for a wide
range of data communications applications.
Optical communications provide the only reliable means of transferring the large
volumes of data at ultra-high speeds needed in today's data centres. The
computing environments in which the data is transferred generally operate at
elevated temperatures which make reliable operation at high temperature an
essential element for the deployment of optical components.
A joint paper published by Chalmers University of Technology and IQE in IEEE
Photonics Technology Letters (Vol. 25, No. 8, pp. 768-771, 2013), reports on the
successful development of VCSEL devices operating at data rates of up to 47
Gbit/s at 25ºC and 40 Gbit/s at 85ºC.
VCSELs provide the primary light source for short-reach optical communication
and currently provide the enabling technology for high capacity optical
interconnect cables in storage area networks such as datacentres and server
farms. VCSEL enabled, multimode fibre optic interconnects optimized for
transmission speed at a wavelength of 850 nm are also used in high performance
computing systems such as computer clusters and supercomputers.
Current high speed optical interconnects use VCSEL technology to operate at
serial data rates of between 10-14 Gbit/s, with devices expected to perform at
25-28 Gbit/s under development. Next generation optical interconnect standards
are expected to require data rates in excess of 40 Gbit/s. Such devices will be
required to operate at the high ambient temperatures expected inside datacomms
equipment.
The results were achieved at a modulation bandwidth of 27GHz at 25ºC and 21GHz
at 85ºC, which is the highest for any VCSEL and the data rate is the highest of
any VCSEL-based optical link without equalization. This is also the first 40
Gbit/s VCSEL operating at elevated temperatures, which is of utmost importance
for practical applications.
The results also generated significant commercial interest when they were
presented at the Optical Fiber Communication Conference (OFC) in Anaheim,
California, last month.
Dr Drew Nelson, CEO of IQE plc, said:
"Photonics applications are emerging as a key enabling technology and the
deployment of devices such as VCSELs is expected to rapidly increase over the
coming years as global data usage grows exponentially.
"IQE has a powerful reputation as a world leader in the development of a range
of photonic devices and is pleased to work with notable experts in the field
such as Chalmers University of Technology in the development of next generation
products"
