Abstract
A multiwavelength LED device including a first LED constructed to emit light of a first wavelength and a second LED constructed to emit light of a second wavelength, different than the first wavelength. The first and second LEDs are stacked vertically on a substrate and positioned to both emit light in the same direction. One of the LEDs is transparent to light emitted by the other of the LEDs so that light from both LEDs is emitted through a single aperture and can be mixed in intensity to produce a variety of wavelengths. The LEDs are individually addressable.
