Exhaustive tests by scientists at Warwick University have confirmed that a revolutionary optical antenna developed on site is three times more powerful than any similar technology in the world today.

Exhaustive tests by scientists at Warwick University have confirmed that a revolutionary optical antenna developed on site is more than three times more powerful than any similar technology in the world today Optical Antenna Solutions (OAS) launched its optical device to the world last November

It has been so inundated with demand from around the world that last month it moved its headquarters to Coventry to be closer to its research and development scientists based at the university.

"The optical antenna has been designed to enhance the concentration efficiency and thus the performance of any receiver used for optical wireless communications - from mobile telephones and laptop computers to automatic tolling roadway systems", said Alex Clarke, Head of Marketing for Optical Antenna Solutions.

"The improvement is dramatic - from three to eight times better, depending on the application.

In this technology field it is like going from the propeller to the jet engine".

The OAS optical antenna has been developed to replace traditional hemispherical lenses currently in use today.

Whereas such lenses have a limited optical gain and a fixed field-of-view (FOV), OAS can provide optical antenna designs having a variety of FOVs and thus higher optical gains than their hemispherical counterparts.

OAS' optical antennas can be designed with a capture angle up to 130 degrees, and they have been engineered to include an optical filter to reject out-of-band radiation that appears as noise at the receiver.

The lens can handle much greater rate of information, over longer distances and can be built both smaller than current technology and to fit any individual requirement.

Experiments carried out on an optical wireless concentrator showed an optical gain.

"We have a programme which allows us to generate a whole range of our antennas to suit any client specification", said Dr Roger Green, Professor of Engineering and Warwick University.

"We can take their specification - design an antenna and generate results to prove the level of enhancement they can expect.

It is taking companies into the next generation of technology without the normal risks associated with it".

Since its launch, OAS has been in negotiations with some of the world's leading semiconductor, photonics and optoelectronic manufacturers.

It also sees huge potential for the device in the automotive, defence and healthcare fields.
