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.
