Patent ID: 7400799

Claim:
An optical device fabrication method of splicing a first optical device and at least one second optical device to fabricate a third optical device, said method comprising the steps of: (a) starting heating of an end surface of said first optical device to soften the end surface; (b) pushing said at least one second optical device into the softened end surface of said first optical device by a predetermined amount so as to splice said first optical device and a joint surface of said at least one second optical device to each other; (c) pulling back said at least one second optical device from the softened end surface of said first optical device to a predetermined position so as to arrange the joint surface of said at least one second optical device into or outside of the end surface of said first optical device; and (d) terminating heating of the end surface of said first optical device so as to fix, said first optical device and said at least one second optical device spliced to each other; wherein step (b) includes pushing said at least one second optical device into the end surface of said first optical device while applying vibrations to at least one of said first optical device and said at least one second optical device.
