ABSTRACT:
A system and method for providing an optical coupler is disclosed. The method and system first places n optical fibers substantially parallel and in close proximity. The number n is odd. The n optical fibers include a center fiber having a first end and a second end. The method and system provide an input signal to the first end of the center fiber and monitor an output signal at the second end of the center fiber. The method and system heat and draw the n optical fibers until the output signal of the center fiber reaches a predetermined value.
