ABSTRACT:
A gradient index codeposition process involving refractive index clipping is used to fabricate rugate filters having multiple reflectance bands. During the codeposition process, whenever the superimposed sine wave profiles extend beyond either the upper or lower refractive index limits of the optical materials involved, the index is held at its bound (i.e., clipped). A rugate filter having a multiplicity of stop bands can be fabricated using a rather limited range of refractive index excursions during the codeposition process. Loss of optical density from index clipping can be corrected by a compensating increase in filter thickness.
