Abstract
A method of manufacturing an optical element, the method comprising: growing a first layer of single crystal diamond material via a chemical vapor deposition technique using a gas phase having a first nitrogen concentration; growing a second layer of single crystal diamond material over said first layer via a chemical vapor deposition technique using a gas phase having a second nitrogen concentration, wherein the second nitrogen concentration is lower than the first nitrogen concentration; forming an optical element from at least a portion of the second layer of single crystal diamond material; and forming an out-coupling structure at a surface of the optical element for increasing out-coupling of light.
