Abstract: An optical connector comprises a sleeve with a flange provided at one end face of a hollow cylinder, a collimator lens, which is press-fitted into or fitted by insertion into the sleeve to be thereafter adhered and fixed to the sleeve, and an optical fiber, which is fusion-bonded at the end face of the collimator lens on the opposite side to the flange side in such a state that the collimator lens is fixed into the sleeve, wherein the end face of the flange is machined to a plane perpendicular to an optical axis, and the collimator lens has a focal position at the end face on the opposite side to the flange side.
Abstract: An optical device fabrication method capable of fabricating optical devices with high precision and reliability in a simple process and at a low cost. The method of splicing a first optical device and a second optical device to fabricate a third optical device includes the steps of: (a) starting heating of an end surface of the first optical device to soften the end surface; (b) pushing the second optical device into the softened end surface to splice the first optical device and a joint surface of the second optical device to each other; (c) pulling back the second optical device to arrange the joint surface of the second optical device onto or outside of the end surface of the first optical device; and (d) terminating heating of the end surface to fix the first and second optical device spliced to each other.
