An optical fiber junction device for coupling a pair of optical fibers with a third optical fiber. A portion of the cladding is etched from the end portions of the pair of fibers, and those end portions are then secured together in side-by-side relationship so that their endfaces are coplanar. The third fiber is so disposed that the end portion thereof is substantially parallel to the end portions of the pair of fibers, and its endface is adjacent to the endfaces of the pair of fibers. Means is provided for causing lateral movement between the endfaces of the pair of fibers and that of the third fiber to vary the amount of light coupled between the pair of fibers and the third fiber.

Variable ratio optical junction device

An optical fiber junction device for permanently coupling a pair of optical fibers with a third optical fiber. The end portions of the pair of fibers are fused together in side-by-side relationship so that their endfaces are coplanar, the cross-sectional area of this structure decreasing toward the endfaces of the pair of fibers. The endface of the third fiber is fused to the endfaces of the pair of fibers.

Optical fiber junction device

A source of optical wave energy for an optical communication system. One end of an optical waveguide fiber bundle is disposed in light-receiving relationship with respect to light from a Lambertian-type light source such as a light emitting diode. A spherical bead of transparent material disposed between the diode and the fiber bundle endface provides a rugged and inexpensive optical device that tends to collimate the light emitted from the diode.
