ABSTRACT:
An optical fiber coupler can include at least a first input optical fiber and an output optical fiber, where the first input optical fiber can comprise an antiguiding core, a first cladding disposed about the antiguiding core and a second cladding disposed about the first cladding so as to tend to confine light to said first cladding. The output fiber can comprise a guiding core, a first cladding disposed about the guiding core and a second cladding disposed about the first cladding of the output fiber for tending to confine light to the first cladding of the output fiber. Optical fibers are also disclosed, as are methods.
