Fiber optic tapered coupler and methods of manufacturing same. One method of manufacturing a fiber optic tapered coupler arrangement includes providing an output fiber having a first end and a second end opposite the first end. The method also includes applying heat to the first end of the output fiber, wherein the first end expands forming a taper at the first end of the output fiber. The method also includes splicing the tapered first end of the output fiber to a first end of an input fiber, wherein a non-tapered portion of the output fiber has a first diameter and the input fiber has a second diameter different from the first diameter.
