To achieve a high transmittance and extinction ratio for the polarized white light-emitting diodes (WLEDs), the package structures of polarized WLEDs that are pumped by blue LEDs are studied. A WLED is implemented using a nano-wire grid polarizer (NWGP) and forms a pumping cavity. Combining the reflection and transmission characteristics of a NWGP, the optimized package structure has an air gap between the phosphor resin and the NWGP. Specifically, the angular dependence of the chromaticity coordinates and spatial uniformity of the radiation pattern are investigated and are more uniform than those of conventional LEDs.
