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