Single-mode single-/dual-window coupler
Fused biconical tapering brings two or more stripped fibers together in a defined arrangement, fuses them under high heat and simultaneously stretches them from both sides to form a special double-taper waveguide in the heated region for optical power coupling. A splitter/coupler distributes one optical input to multiple or two outputs, or combines multiple or two inputs into one output. Port configurations include X, Y, star and tree couplers.
