Abstract
Core configuration transformers and methods of making same. A core configuration transformer includes a transforming optical fiber having plurality of routing cores embedded therein. The transforming optical fiber includes a first end face and a second end face. The plurality of routing cores is configured to define a first end face core pattern at the first end face of the transforming optical fiber, and a second end face core pattern at the second end face of the transforming optical fiber that has one or both of a different arrangement of cores or a different polarity of cores.

A method of making a core configuration transformer, comprising:
- splicing a first end of a length of coreless optical fiber to a first end face of a first multicore optical fiber including a first plurality of cores that define a first end face core pattern at the first end face;
- splicing a second end of the length of coreless optical fiber to a second end face of a second multicore optical fiber including a second plurality of cores that define a second end face core pattern at the second end face different from the first end face core pattern;
- and
- defining a transforming optical fiber by writing a plurality of routing cores in the length of coreless optical fiber each configured to operatively couple a respective core of the first plurality of cores to a respective core of the second plurality of cores.
