Abstract
A system and method which integrates a mirror at the fiber tip to the fiber tip and uses a tilted flat at the exit plane to prevent astigmatism caused by the cylindrical curvature of the fiber wall and minimize reflection.
Claims24
A reduced reflection, lateral output optical fiber comprising:
- an optical emitting fiber having a core and a cladding;
- a mirror positioned to deflect light from the core laterally through the cladding;
- and
- a tilted flat formed on the cladding around an exit plane of the deflected light, wherein the tilted flat is tapered or flared with respect to a planar surface parallel to an axial centerline of the optical emitting fiber.

A method for making a reduced reflection, lateral output optical fiber comprising:
- providing an optical emitting fiber having a core and a cladding;
- forming a mirror at an end of the optical emitting fiber, said mirror being positioned to deflect light from the core laterally through the cladding;
- and
- forming a tilted flat on the cladding at an exit plane for light deflected by the mirror wherein the tilted flat is tapered or flared with respect to a planar surface parallel to an axial centerline of the optical emitting fiber.
1 more element
A method for reducing reflection and astigmatism of light exiting an optical emitting fiber at an angle other than 0° comprising:
- forming a mirror at an end of the optical emitting fiber, said mirror being positioned to deflect light from the core laterally through the cladding;
- and
- forming a tilted flat on the cladding at an exit plane for light deflected by the mirror, wherein the tilted flat is tapered or flared with respect to a planar surface parallel to an axial centerline of the optical emitting fiber.
