ABSTRACT:
A coupler for coupling light from one single mode optical fiber to another. Two or more optical fibers are provided in twisted or braided adjacency so that the evanescent field of one optical fiber is coupled into at least one other fiber for dividing the power therebetween. Means are provided for coextensively supporting and encapsulating the optical fibers to stabilize and protect them under demanding environmental conditions resulting from temperature variations, physical shock and vibration.
