ABSTRACT:
A lens having at least one oxidized layer is provided. Numerous structures for the lens are discussed. Additionally, methods for manufacturing the lens are also discussed. The methods include: 1) variation in thickness of oxidizable layers; 2) variation in thickness of non-oxidizable layers; 3) variation in Al concentration of oxidizable layers; 4) variation in Al concentration of non-oxidizable layers; 5) variation in doping concentration of oxidizable layers; 6) use of interdiffusion between oxidizable and non-oxidizable; 7) local variation in ion implantation dose; and 8) variation in mesa diameter.
