Splash is a collaborative project between researchers in St Andrews, Glasgow, Milan, Paris, Amsterdam and Australia that is funded by the European Union under the sixth framework programme as a Future and Emerging Technologies (FET) open project. For a list of these projects, please follow the link to CORDIS website.
Our aim is to make optical switches and storage devices based on slow light that may be used in the next generation of all-optical data processing systems. Such systems will support the increasing speed and bandwidth needed to satisfy the raising demands of consumers for online video, music and other data.
Data is currently sent over the internet as pulses of light in optical fibres. However, to get from place to place – to route or switch it – the data must be converted from optical signals to electrical ones, before being processed by electronic components and converted back to light. Removing the bottleneck of this conversion has the potential to speed up internet connections and to reduce the power needed for operating future internet systems. In order to do this, compact and cheap optical switches are needed that can route optical signals without any conversion to electrical signals. A related device, called a delay line, is also needed. A delay line acts as a storage or memory element for the short time, or delay, that it takes for the signal to be routed to the correct place.
The consortium is open to industrial collaborations in view of exploitation of slow light devices.
