Abstract
PQR lasers with ultra-low threshold current and sharp discrete multi-mode properties can outdo conventional LEDs. We have confirmed many advantages of low injection, high efficiency, high frequency PQR arrays over the conventional LEDs. We also present blue PQR laser arrays from GaN structures, which are promising for display applications as well as high efficiency solid state lighting.
