英文摘要	Fiber optic couplers formed of at least two single mode optical fibers, at least one of which is an input fiber, are shown, the fibers constructed and arranged in the manner that coupling between the input fiber and the other fibers limits antisymmetric modal energy to substantially less than 50% of the input energy, the coupling region of said coupler being fused and drawn to an extended length sufficient to cause cutoff of the antisymmetric mode energy, whereby the coupler exhibits coupling ratio stability over an extended range of wavelengths and an excess loss of substantially less than 50%. Numerous fiber couplers of various construction, all employing cut-off of the antisymmetric mode to achieve wideband response or wavelength insensitivity are shown along with their method of manufacture.
