III-V nitride-based LEDs and lasers: Current status and future opportunities

Abstract

Solid-state lighting is based on short wavelength nitride-based light emitting diodes (LEDs) or laser diodes (LDs), that can produce white light. Presently, nitride-based LEDs have efficiencies exceeding those of incandescent light bulbs and most likely, will surpass those of fluorescent lights in the near future. In this talk, the latest performance of nitride-based ultraviolet (UV)/blue/green/amber/white LEDs and violet/blue LDs will be discussed.
