Blue laser diode (LD) and light emitting diode (LED) applications

201_12/2004In the ‘LED Highlight’ session at the 5th International Symposium on Blue Laser and Light Emitting Diodes (ISBLLED-2004), held in Gyeongju, Korea, 15–19 March 2004, Arpad A. Bergh [1] gave an overview on current and future LD and LED applications including prospects for industry and market developments. Papers from this session can be found in a special coloured section of this issue on pages 2730–2754.

The cover picture shows a GaN vertical cavity surface emitting laser (VCSEL) array for white light illumination, designed to raise the light extraction efficieny of the device above 60% (courtesy of S. Nakamura, UCSB).

Further papers from ISBLLED-2004 are published in phys. stat. sol. (b) 241, No. 12 (2004) and phys. stat. sol. (c) 1, No. 10 (2004).
