Micro-pixel flip-chip AlInGaN LED arrays with high CW and nanosecond output power

摘要

Flip-chip AlInGaN micro-LED arrays with different wavelengths and pixel diameters have been fabricated, giving, per pixel, CW output power densities up to 32.5 W/cm 2 at 20 mA and pulsed output of up to 150 pJ in 36 ns pulses.
