Abstract: GaN-based dual-wavelength light emitting diodes (LEDs) with different In contents in the wells and barriers was designed and fabrieated in our experiment. Electroluminescence of the fabricated LED at the typical driving current of 20mA has two colors,blue and green respectively. The ratio of the intensities of the green light to the blue light increases with increasing driving current. At larger current,the blue shift of the peak wavelength of the green light was greater than that of the blue light. We are also concerned with the effect of polarization and non-uniform carrier distribution in the active region. Using coupled method of simulation,the calculated data were consistent with the experiment.
