Abstract
The invention relates to an optical fiber and a fiber termination which provide an output of laser light propagating through the fiber in a required direction while focusing it into a small spot. In one embodiment of the invention the termination includes a tapered fiber rod with an angled ball formed at the end of the rod. A corresponding method of manufacturing of the termination is provided. In another embodiment the termination includes a fiber rod having an angled end and a GRIN lens disposed so as to receive light reflected from the angled end, the lens being an integral part of the termination. In other embodiments the lens is replaced with a cylindrical or tapered multimode stub which provide similar function.
Claims20
An optical fiber having an optical element formed at an end of the fiber,
- said element being comprised of an angled fiber end and a lens for providing an output of a light beam, propagating through the fiber, in a direction traverse to the direction of the beam propagation while reshaping the beam into a spot of a required shape and size, said lens being disposed so as to receive the beam reflected from the angled fiber end and said fiber further comprises a groove for receiving said lens.
An optical fiber termination, comprising an optical element formed at one end thereof,
- the element being designed so that, when the termination is being coupled to a fiber, to provide an output of a light beam, propagating through the fiber, in a direction traverse to the direction of the beam propagation while reshaping the beam into a spot of a required shape and size,
- the element being an integral part of the termination, and being further comprised of an angled fiber end and a lens, the fiber end having a groove to receive the lens and the lens being disposed so as to receive the beam reflected from the angled fiber end.
