    Abstract: A light emitting device includes a substrate having a surface region and a light emitting diode overlying the surface region. The light emitting diode is fabricated on a semipolar or nonpolar GaN containing substrate and emits electromagnetic radiation of a first wavelength. The diode includes a quantum well region characterized by an electron wave function and a hole wave function. The electron wave function and the hole wave function are substantially overlapped within a predetermined spatial region of the quantum well region. The device has a transparent phosphor overlying the light emitting diode. The phosphor is excited by the substantially polarized emission to emit electromagnetic radiation of a second wavelength.
