1. A method of manufacturing a graded refractive-index plastic optical-fiber, said method comprising:

  • preparing a base polymer and a monomer-containing solution;

    preparing a fiber material from said base polymer and including a non-polymerizable compound having a refractive index higher than that of said polymer;

    heating and melting said fiber material to obtain a melt;

    continuously spinning said melt to form a fiber;

    dipping said fiber in said monomer-containing solution and impregnating said fiber therewith, so that each of said monomer and said non-polymerizable compound are diffused in said fiber; and

    curing and hardening said monomer.
