InGaN RGB Light-Emitting Diodes With Monolithically Integrated Photodetectors for Stabilizing Color Chromaticity

In this paper, a solution toward realizing color chromaticity stabilized InGaN red, green, and blue (RGB) light-emitting diode (LED) is proposed and demonstrated. The InGaN/GaN multiple quantum wells (play a key role in light emission from the LEDs and photodetection from the photodetectors (PDs). The spectral overlaps between the emission and absorption spectra are measured and the photocurrents of the PDs exhibit linear behavior with...
