Figure 4From: Influence of patterned sapphire substrates with different symmetry on the light output power of InGaN-based LEDsTracePro ray tracing results for the InGaN-based LEDs having the CSS, HLAPSS, and SLAPSS. The associated LEE with different samples is evaluated from the bare LED simulation results, and the insets show the cross-sectional ray tracing image.Back to article page
