Osram Opto Semiconductors Inc. of San Jose, Calif., said it has developed the first polymer-OLED tunable light source and achieved a 25 lumens-per-watt (lm/W) device efficiency as part of a white organic light-emitting diode (OLED) project funded by the US Department of Energy (DOE). The $4.65 million grant was awarded in 2004 to research the potential of white OLEDs to save energy in commercial and residential lighting applications. Osram said the cool-white-emitting device uses a phosphorescent, blue-emitting device in conjunction with an external inorganic phosphor layer. The tunable light source is the industry's first OLED demonstration based on three separate, printable polymer inks emitting in the red, green and blue portion of the spectrum, the company said.    . . .    Picometrix LLC, an Ann Arbor, Mich., maker of optoelectronic components and products, said it has received orders totaling more than $1 million for its T-Ray 2000 terahertz (THz) system from the New Jersey Institute of Technology, the University of Adelaide, a US defense contractor and a foreign national lab. The systems order will be fulfilled over the next two quarters. The T-Ray 2000, which is capable of THz spectroscopy and imaging, is used for application development. Picometrix is a subsidiary of Advanced Photonix Inc., a Camarillo, Calif., manufacturer of silicon photodetectors and optoelectronic assemblies.
