Patent Images
1. An apparatus for coupling light between an optical fiber and a light element, comprising:
- a light element;
a resiliently deformable material having a first surface in contact with a first optical fiber;
means for preventing deformation of a second surface of the resiliently deformable material through which light passes when coupled or decoupled with the first optical fiber through a side thereof, the light element being disposed outside the resiliently deformable material, the deformation prevention means comprising a hard transparent member disposed in contact with the second surface;
a container for containing and enclosing the resiliently deformable material about all external surfaces thereof in conjunction with the hard transparent member except for the first surface, the container having an opening therein in a vicinity of the hard transparent member, and another opening therein in a vicinity of the first surface.

Abstract
An apparatus for injecting light into or withdrawing light from an optical fiber using a resiliently deformable material includes a hard transparent member disposed in contact with a surface of the resiliently deformable material in a vicinity of a light element which minimizes material creep of the resiliently deformable material in a vicinity of the light element which stabilizes a coupling and decoupling efficiency with an optical fiber.
