Abstract
A sealing composition for a photonic crystal fiber which comprises a compound represented by the following general formula (I), a compound represented by the following general formula (II) and a photo-polymerization initiator: Tf1-(O)—(CH)—(CF)—(CH)—(O)-Tf1 (I) Tf2-(O)—(CH)—(CF)—(CH)—(O)-Tf2 (II) wherein a represents 0 or 1, b represents 0 or 1, m represents an integer of 4 to 12, Tf1 represents a glycidyl group, and Tf2 represents CH═CH—C(O)—; and a method for producing an optical fiber comprising filling air holes with above sealing composition and polishing and end surface; and an optical fiber having air holes in the inside which is produced by the method. The above sealing composition can achieve a low refractive index, and also is excellent in the low viscosity and heat resistance, and exhibits good filling characteristics and good polishing processability.
