ABSTRACT:
The invention relates to a broad-band light emitting diode having an active layer composed of a plurality of light emission regions of differing materials for emitting light at a plurality of wavelengths, wherein each of the emission regions of the active layer is electrically controlled by a separate electrode for providing a broad-band emission or optical gain with a multi-point control of its spectral profile.
