Abstract
This invention provides a semiconductor light emitting device having multiple quantum wells with modulation-doping. The present device has a structure of quantum well layers and barrier layers inter-disposed with each other. These quantum well layers have the same material composition proportion but different thicknesses so as to produce different light wavelengths. The barrier layers of the present invention are performed modulation-doping with respective dopant concentrations. As such, the intensity of illumination of each quantum well layer is controllable. The characteristic of illumination of the whole device is variable so as to improve the broadband quality.
