Abstract:
A device may include a wavelength converting layer on an epitaxial layer. The wavelength converting layer may include a first surface having a width that is equal to a width of the epitaxial layer, a second surface having a width that is less than the width of the first surface, and angled sidewalls. A conformal non-emission layer may be formed on the angled sidewalls and sidewalls of the epitaxial layer, such that the second surface of the wavelength converting layer is exposed.
