Abstract

See full text

A method of forming a light conversion element includes providing a semiconductor construction having a first photoluminescent element epitaxially grown together with a second photoluminescent element. A first region is etched in the first photoluminescent element from a first side of the semiconductor construction and a second region is etched in the second photoluminescent element from a second side of the semiconductor construction. In some embodiments the wavelength converter is attached to an electroluminescent element, such as a light emitting diode (LED).
