A POF includes an inner core having a refractive index distribution and an outer core provided on periphery of the inner core. A ratio Ra/Rb of an outer diameter of the inner core to the outer core satisfies 0.67≦(Ra/Rb)≦0.87 such that an outgoing beam from an end of the POF may have a parallel area of at least 200 μm. Thus a space between the end for exiting the exit light and a light receiving device can be kept at least 200 mm without members or devices for collimating.

A polymerization initiator, a first polymerizable compound, and a second polymerizable compound are poured into a hollow of a first member (12). The first and second polymerizable compounds are copolymerized to produce a second member (16). The second member (16) is produced by forming a first layer (21) on an inner wall of the first member (12) and sequentially forming a layer over a precedingly formed layer. To form each layer, the first and second polymerizable compounds are put in the hollow of the first member (12), satisfying 1/99≦W2/(W1+W2)≦2/3 when W1 is a weight of the first polymerizable compound, and W2 is a weight of the second polymerizable compound. The first and second polymerizable compounds are mixed such that the value of W2/(W1+W2) increases from the first layer (21) toward an nth layer.

摘要:
A method for producing a plastic optical device having refractive index profile, which comprises filling the hollow of a hollow plastic structure with at least one non-polymerizable compound having a refractive index higher by at least 0.001 than that of the plastic structure, and diffusing the non-polymerizable compound into the plastic structure. The method gives a plastic optical device having refractive index profile free from a problem of loss increase owing to thermal deterioration or depolymerization.

A core (33) is formed by polymerization of core material that is poured in a hollow part of a tubular inner clad (19) formed inside an outer clad (18). The inner core material comprises a first core monomer having the structural unit of the inner clad (19), a second core monomer different from the first core monomer, and a non-polymerizable refractive index control agent. While the first and second core monomers are copolymerized, the concentration of the refractive index control agent in the core (33) is gradually changed to generate a refractive index profile in the core (33). The second structural unit is the second core monomer can improve heat-resistance of the core (33), and prevent microscopic phase-separation near the interface between the inner clad (19) and the core (33).
