Abstract
One or more optical fibers are attached to an optical component element or supporting substrate by coating the peripheral surface of the optical fiber with a metallic layer and then positioning the metallic layer in electrical contact with a metal surface of the object along an interface. An electrical current pulse or pulses is applied through the interface sufficient to cause local melting or near melting and welding at the interface.
Claims21
A method for bonding an optical fiber to an object having a metal surface, comprising:
- (a) coating at least a portion of the periphery of the optical fiber with a metallic layer in the area of the fiber where bonding is to take place;
- (b) positioning said metallic layer in electrical contact with the metal surface of said object along an interface between the fiber and the object;
- and
- (c) applying at least one preselected and controlled electrical current pulse through said interface sufficient to cause local melting of the metallic surfaces and welding at the interface.
