Including news from BridgeLux, CIP, Aixtron, Avago Technologies, and others.
• Konica Minolta has developed an organic light-emitting diode with a brightness of 1000 cd/m2 and an expected lifetime of 10,000 hours, according to a report on the DigiTimes website. Running with an efficiency of 64 lm/W, the device can be used as a backlight for handset displays or for general lighting applications. The device can also emit light of different color tones to mimic the output of an incandescent bulb or fluorescent light.
• Preliminary second-quarter results from Alliance Fiber Optic Products (AFOP), indicate net sales of $6 m, exceeding earlier guidance figures given by the company. If confirmed, the results would be an increase of almost 15% on the first-quarter sales figures of $5.22 m.
• Silecs, a supplier of materials to the microelectronics industry, has introduced a series of optical coatings for use with CMOS image sensors. The optically tuned films that make up the SC product series have been designed to improve the reliability and optical efficiency of CMOS image sensors, while low-temperature processing and direct photo-patterning ensure low manufacturing costs.
• High-power LED chip manufacturer BridgeLux (formerly eLite Optoelectronics) has introduced what it claims is the only 60-mil (1.5 mm) chip available in production volumes today. The blue-emitting chip, which is one in a family of KO blue devices, can support a drive current of up to 1.2 A. When combined with phosphors to generate white light, the chip can produce a luminous flux of 140 lm.
• CIP, a UK-based manufacturer of photonic hybrid integrated circuits and InP-based optoelectronic chips, has won a contract as part of a project to develop a portable DNA analyser for use at crime scenes. The three-year project will be led by the University of Hull, and CIP's role will be to develop a miniaturized optical detection and analysis system for subsequent integration with a micro-fluidic lab-on-a-chip. CIP's system will exploit an electrophoretic separation step coupled with a detection system that will stimulate and detect fluorescence in the sample.
• Ricoh has developed an optical part that can read both Blu-ray and HD-DVD next-generation formats, according to a report on Nikkei.net. While both Blu-ray disc and HD-DVD technologies use blue lasers to read and write data, Blu-ray requires a wider laser beam and the two rival formats record data at different depths (0.1 mm for Blu-ray; 0.6 mm for HD-DVD). Ricoh claims that its optical part alters the depth of the laser's focal point, and is now planning to develop the technology into an optical head that will be sold to optical drive manufacturers.
• Epitech Technology Corporation of Taiwan is to install a new MOCVD reactor from German equipment maker AIXTRON. The recently released Thomas Swan CRIUS MOCVD reactor, which has a wafer capacity of 30 2-inch wafers, will be used for the mass production of ultrahigh-brightness GaN-based LEDs. The reactor will be installed in Epitech's state-of-the-art facility in Tainan, Taiwan.
• Avago Technologies has introduced what it claims is the first RGB color sensor that meets the specifications set down for automotive applications. The CMOS sensor is intended to be used inside vehicles to convert colored light into red, green and blue voltage outputs. Such outputs could be used for open- or closed-loop optical feedback for light sources in navigational panels, and for dashboard and interior lighting. The sensor meets the specifications laid down for integrated circuits by the Automobile Electronics Council.
