Abstract
A packaged optical device includes a substrate having a surface region with light emitting diode devices fabricated on a semipolar or nonpolar GaN substrate. The LEDs emit polarized light and are characterized by an overlapped electron wave function and a hole wave function. Phosphors within the package are excited by the polarized light and, in response, emit electromagnetic radiation of a second wavelength.
