Abstract: A fiber optic coupler comprising a plurality of single-mode optical fibers, each of which is tapered to form a small diameter section that extends in contiguous relationship with the small diameter sections of the other fibers to form a coupling region. Each of the fibers has a core surrounded by a cladding of refractive index lower than that of the core. At least one of the fibers has a refractive index pedestal of refractive index ni between said core and cladding, wherein n1>ni>n2, n1 and n2 being the refractive indices of the core and cladding, respectively.
