Patent abstract

The present invention has a core and at least one cladding, where, by changing the temperature of the cladding, the material dispersion characteristic of the cladding is changed and a refractive index is varied to make fundamental-mode cutoff tunable as well; and the difference between dispersion slopes of core and cladding is crucial to the sharpness of the fundamental-mode cutoff.
