MICROLENS COMPRISING A GROUP III-NITRIDE MATERIAL

摘要

Microlenses and microlens arrays according to the invention are based on Group III-nitride materials. As used herein, "Group III" represent the elements in the Periodic Classification of Elements Charts that includes Boron (B), Aluminium (A1), Galium (Ga), Indium (In), and Thallium (T1), and alloys. In certain embodiments, the microlenses are durable in challenging environments such as higher temperatures and exposure to chemicals and/or radiation. In one aspect, the invention provides microlenses made from Group III-nitride materials. The microlenses and arrays thereof are transmissive to electromagnetic radiation, particularly in the green through ultra-violet light spectrum. In another aspect, an embodiment of the invention includes a system having an opto-electric device and a microlens made from Group III-nitride material. Another aspect of the invention is a method of making microlenses from Group III-nitride materials.
