Abstract
There is herein described a patterned thin-film wavelength converter which comprises a substrate having a first patterned surface with a first pattern, and a thin film deposited on the first patterned surface. The thin film consists of a wavelength converting material and has a second patterned surface that is distal from the substrate. The second patterned surface has a second pattern that is substantially the same as the first pattern of the substrate. An advantage of the patterned thin-film wavelength converter is that post-deposition processing is not required to produce a textured surface on the wavelength converting material. A method of making the patterned thin-film wavelength converter is also described.
