Claim 0:
1. A method for producing a multicore optical fiber, the method comprising:
providing a transparent polymer whose index of refraction is increasable by irradiation that induces photopolymerization of the transparent polymer;
providing a source of radiation that is capable of inducing photopolymerization in the transparent polymer; and
directing the radiation by one or more optical components to a plurality of elongated regions within the transparent polymer to induce the photopolymerization of the transparent polymer within the plurality of elongated regions, each of the elongated regions surrounded by a region of the transparent polymer that was not photopolymerized, such that in an optical fiber that is formed of the transparent polymer after the photopolymerization, each of the elongated regions functions as a core of the optical fiber and the region that surrounds each of the elongated regions functions as a cladding of each of the cores.
