TDI and Ostendo has jointly made a breakthrough on semi-polar (11-22) GaN wafers which are more than 2.5x the emission intensity of c-plane GaN based LED structures. These results have in common with the research conducted by Sumitomo Electric Industries who discovered that green laser diodes (LD) grown on the semi-polar GaN plane are more efficient than those grown on the conventional c plane.

Ostendo Technologies Inc. and Technologies and Devices International, Inc. (TDI), part of the Oxford Instruments Group, announce their joint development on Semi-Polar (11-22) GaN layer on sapphire substrate wafers is now available.

Not content to rest after being awarded a LEED Silver certification, The Hilton Ocala Hotel in Ocala, FL had a desire to become even greener and more energy-efficient. That desire led the company to install LED lighting in the lobby and other public spaces throughout the hotel. As Ocala’s premier hotel, the management felt the need to lead by example by finding and using new technologies and products to conserve energy, reduce their carbon footprint and lower operating costs.

Technologies and Devices International, Inc. (TDI), part of the Oxford Instruments Group, today announced it has been awarded $600,000 by the Maryland Energy Administration to help industry expedite the broad adoption of energy-efficient LED lighting, and better position Maryland to become a national solid-state lighting materials and equipment manufacturing leader.
