Abstract

An evanescent field coupler comprising a coupler holder, a first optical fiber mounted in a first substrate block, and a second optical fiber mounted in a second substrate block. The first substrate block is compliantly mounted to the holder. Means are included for positioning the substrate blocks with respect to the other for switching and adjustment of the coupling ratio. The compliant mount elastically deforms during switching and/or alignment to facilitate accurate, repeatable switching, while maintaining the desired coupling ratio between the optical fibers.
