Method of fabricating an optical element. A photodefinable composition is provided that includes (i) a hydrophobic, photodefinable polymer, said photodefinable polymer having a glass transition temperature in the cured state of at least about 80° C.; and (ii) a multiphoton photoinitiator system comprising at least one multiphoton photosensitizer and preferably at least one phtoinitiator that is capable of being photosensitized by the photosensitizer. One or more portions of the composition are imagewise exposed to the electromagnetic energy under conditions effective to photodefinably form at least a portion of a three-dimensional optical element.
A method of fabricating a three dimensional optical element, comprising the steps of:
