Abstract
An optical structure is fabricated by forming an active layer including a photodefinable material on a substrate or on another underlying layer, forming an upper layer above the active layer, and then patterning the active layer by selective application of radiation through the upper layer. The upper layer is substantially transparent to radiation of the type required to activate the photodefinable material in the active layer.
