Abstract:
A device for selectively increasing higher-order mode losses comprises an optical fiber taper executed on a multi-mode fiber of a selected wavelength, and the fiber taper has separated regions, i.e. non-tapered fiber regions which have a first diameter equal to that of the main fiber. The tapered regions can also include transition regions in which the fiber diameter is reduced/increased, respectively, and a taper waist region which has a reduced diameter, where the taper level ratio between the regular diameter and the narrowed diameter is at least 20%, and the length of the transition regions are at least 0.5 mm on one side and may be zero on the other side, and the length of the taper waist with the narrower diameter is at least 0.5 mm. Furthermore, the taper area is coated with a filtering substance with attenuating properties between the tapered section and the cladding.

Claim (Index 9):
The device of  claim 1 , further comprising:\n an optical fiber cladding material surrounding the optical fiber taper; and wherein the filtering substance has a higher refractive index than a refractive index of the optical fiber cladding material.
