Original Abstract Submitted
A method of producing a light emitting diode (LED) array comprises: forming a plurality of layers of semiconductor material; forming a dielectric mask layer over the plurality of layers, the dielectric mask layer having an array of holes through it each exposing an area of one of the layers of semiconductor material, and growing an LED structure in each of the holes arranged to emit light over a range of wavelengths. At least some of the plurality layers form a distributed Bragg reflector (DBR) arranged to reflect light of at least some of said range of wavelengths.
