Abstract
Abstract ABSTRACT OF THE DISCLOSURE There is disclosed an optical coupler for coupling optical energy to or from optical fibers. The coupler comprises an optically transparent cylinder in which there is located a biconical tapered section and at least one parallely adjacent single tapered section whose taper is selectively positioned with respect to the mid-point of the biconical section.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
146 words
THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS: l. A bi-directional optical coupler for coupling optical energy between optical fibers comprising in combination: an internally reflective body adapted to reflect radiation modes of optical energy which have been converted from guided modes; a first single port optical fiber having a nominal diameter terminating in said body as a single longitudinal tapered section converging substantially to a point; and a second optical fiber located in said body, having respective ports at either end and including a pair of intermediate tapered conical sections joined to a region of reduced diameter, said first and second optical fibers being located and adjacent one another with the point of said first optical fiber being selectively positioned relative to the region of reduced diameter between said tapered regions of said second fiber.
Claim 2
Dependent Claim
17 words
The coupler as defined by claim 1 wherein said internally reflective body comprises an optically transparent cylinder.
Claim 3
Dependent Claim
31 words
The coupler as defined by claim 1 wherein said point of said first optical fiber extends laterally to substantially the mid-point of said region of reduced diameter of said second fiber.
Claim 4
Dependent Claim
34 words
The coupler as defined by claim l wherein said point of said first fiber is displaced laterally a predetermined distance away from the mid-point of said region of reduced diameter of said second fiber.
Claim 5
Dependent Claim
50 words
The optical coupler as defined by claim l and additionally including at least one additional optical fiber like said first recited single port optical fiber and whereby said two like single port optical fibers are located parallely adjacent said second optical fiber in the region of one tapered section thereof.
Claim 6
Dependent Claim
35 words
The coupler as defined by claim 5 wherein said two like optical fibers have tapered end points which are laterally displaced away from the mid-point of said region of reduced diameter of said second fiber.
Claim 7
Dependent Claim
50 words
The coupler as defined by claim 1 and additionally including two more optical fibers like said first recited single port optical fiber, and all of said like single port optical fibers being positioned parallely around and adjacent a common region of said second optical fiber inside said internally reflective body.
