A method of forming a coupler (120) includes the steps of: (a) heating a portion (110) of an optical fiber (101) having multiple cores (201) and an initial diameter (di); and (b) applying a tensile force (103) across the portion such that the portion stretches, thereby reducing the initial diameter (di) to a reduced diameter (dr) sufficient to cause optical signals propagating in one or more of the multiple cores to leave their respective cores and enter other cores of the fiber. |
