Abstract

In this work, spectral competition of chirped dual-wavelength emission in monolithic InGaN multiple-quantum well (MQW) light-emitting diodes (LEDs) is studied numerically. In addition to the crystalline quality that is generally desired for good LED performance, the simulation results show that effective suppression of piezoelectric polarization is another key issue toward the realization of efficient monolithic dual-wavelength emission in InGaN MQW LEDs. With appropriately tailored configuration of MQW active region, the detrimental effects of hetero-interfaces and polarization charges are diminished and thereby balanced dual-wavelength emission can be achieved.
