Electronic function built into optical fibre
01 May, 2006A joint team from the University of Southampton in Britain and Penn State University in the US has combined the technologies of optical fibre and silicon/germanium to make devices inside microstructured fibres.
Circuit elements for opto frequencies
10 September, 2005Researchers at the University of Pennsylvania propose to shrink circuits to save space and power and, more importantly, accommodate electronic applications at much higher frequencies than are possible with current models - applications that include nano-optics, optical information storage and molecular signalling.
Light beams tied in knots
15 July, 2005Researchers from the British universities of Southampton and Glasgow have succeeded in tying knots in light beams.
Optical modulators
18 March, 2005The Centre for Integrated Photonics in Ipswich, England has launched a range of electro-absorption modulators fabricated using indium-phosphide.
New twist on fibre optics
14 October, 2004By twisting fibre optic strands into helical shapes, researchers have created unique structures that can precisely filter, polarise or scatter light.
Optical research boosted
19 August, 2004The low yield of optical semiconductor processing, compared with today's silicon industry, is stalling progress in major markets such as ultra-high bandwidth communications networks for enterprises and homes.
Breakthrough in silicon photonics
05 October, 2003Silicon, one of the base elements of our planet, is the foundation of the modern information society. Modern electronics would be unthinkable without the development of silicon transistors
Research centre for photonics
05 May, 2003Many items in everyday use - such as mobile phones and laptop computers - exist because of research carried out in photonics. At the UKs University of Cambridge, several academic groups have joined with industrial partners to investigate the different aspects of photonics, applications and materials in a new Centre for Molecular Materials for Photonics and Electronics (CMMPE).
Fibre-delivery laser
15 April, 2003Agilent says it has released what it claims is the first laser with fibre optic delivery suitable for the demands of next-generation lithography motion control.
Tunable optical fibres
04 March, 2003Optical fibres regularly carry billions of phone conversations and other data transmissions every day and are a fundamental part of optical sensing and numerous medical applications. The photonic devices responsible for this traffic are being made even more efficient and versatile by handing over some of the switching and reconfiguring chores to the fibres themselves - the trunk lines linking all the optical nodes.
High speed optocouplers
04 December, 2002Agilent has introduced high speed optocouplers, claimed to be capable of transmitting data at a 50 megabaud (MBd) rate, allowing high speed collection and control in industrial automation applications where isolation is required.
Pluggable optic transceiver standard
27 September, 2002Zarlink Semiconductor and Agilent have announced a multi-source agreement intended to create a common standard for pluggable 4-channel parallel optic transceiver modules that offer an aggregate bandwidth of up to 10 Gb/s.
Helium recovery helps fibre optic production
05 September, 2002BOC's fibre optics solutions group has patented a helium recovery system capable of capturing and recycling more than 85% of the helium used in optical fibre production
Erbium-Doped Fibres
09 August, 2002Semrock has made available a line of erbium-doped fibres. The fibre portfolio consists of both C-Band and L-Band fibres, in 125 and 80 micron cladding diameters.
