A hybrid sol-gel material (42) is placed in optical contact with two optical surfaces (36,38) and the surfaces are precisely aligned as necessary to meet desired optical specifications. The sol-gel material filling the gap between the surfaces is then cured, such as by exposure to UV radiation This allows, for example, the fabrication of a solid-spaced etalon filter where the spacer layer of the etalon is formed with sol-gel material to a precise dimension defined by the alignment of the optical surfaces. The optical properties of the hybrid-glass structure formed between the optical surfaces may be fine tuned by varying the exposure of the sol-gel material to the curing agent. Furthermore, the hybrid-glass structure of the invention can be patterned using standard photolithographic techniques. |
