Abstract
A connecting structure of an optical fiber to an optical waveguide includes a circular cylindrical holder having a bore with a circular cross-section communicating one end thereof to the other. The protecting layer removal end of the optical fiber is inserted into the bore. An end plane of the protecting layer removal end and a side plane of the holder are co-planar to be connected to an end surface of an optical waveguide.
Claims21
An optical fiber connecting structure for an end plane of an optical fiber, said optical fiber connecting structure, comprising:
- an optical fiber having a protecting layer thereon, a predetermined length of said protecting layer being removed in the vicinity of said end plane of said optical fiber to form a protecting layer removal end;
- and
- a holder for holding said protecting layer removal end, said holder being provided with a bore of circular cross-section for receiving said protecting layer removal end from one side plane of said holder to another;
- wherein said another side plane of said holder is co-planar with said end plane of said optical fiber.
An optical fiber connecting structure for an end plane of an optical fiber, comprising:
- a polarization-maintaining optical fiber having a protecting layer thereon, a predetermined length of said protecting layer being removed in the vicinity of said end plane of said optical fiber to form a protecting layer removal end;
- and
- a holder for holding said protecting layer removal end, said holder being provided with a bore of circular cross-section for receiving said protecting layer removal end from one side plane of said holder to another;
- wherein said another side plane of said holder is co-planar with said end plane of said optical fiber, such that a direction of one of the birefringence axes of said optical fiber is parallel to said side plane of said holder.
