Unique optical hybrid technology from QinetiQ
Unique optical hybrid technology from QinetiQ
Keywords: QinetiQ
A new technology that enables high quality all-optical networks has been developed by QinetiQ. The optical hybrid technology, which improves performance while reducing expenditure, employs a radical hollow waveguide (HWG). The HWG has the potential to cut more than 50 per cent of the cost of complete optical circuits.
The unique QinetiQ technology uses a simple and structured architecture, enabling light to be guided directly from device to device across a large area. This overcomes the problems of beam divergence and alignment accuracy. The conventional rib waveguide structure is turned on its head and instead a "hollow" guide is used.
The HGW is etched or cut from a flat substrate to provide a guide channel in the material. The guide performance may be enhanced by coating the guide walls to alter its optical properties. A lid is attached to provide the fourth guide wall.
