Abstract
A multicore optical fiber with an integral diffractive element. The multicore optical fiber includes: a first optical fiber core formed of a non-photosensitive material having an initial index of refraction; and a second optical fiber core including a second longitudinal core axis substantially parallel to the first longitudinal axis. The first optical fiber core includes: a first longitudinal core axis; and a number of index-altered portions having an altered index of refraction which is different from the initial index of refraction. The index-altered portions are arranged within the non-photosensitive material of the first optical fiber core to form a diffractive structure of the integral diffractive element.
