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 1):
A device for selectively increasing higher-order mode losses in a fiber communication system, comprising:\n an optical fiber taper, configured to be connected to a multi-mode fiber of a selected wavelength, the optical fiber taper comprising:\n a first non-tapered region and a second non-tapered region, each having a diameter equal to a diameter of the multi-mode fiber; \n a waist region having a diameter that is smaller than the diameter of the first and second non-tapered regions; \n a first transition region between the first non-tapered region and the waist region having a diameter that transitions from that of the first non-tapered region where the first transition region meets the first non-tapered region to that of the waist region where the first transition region meets the waist region; \n wherein a ratio of taper is defined by a ratio of a difference in diameter between the diameter of the first and second non-tapered regions and the diameter of the waist region over the diameter of the first and second non-tapered regions, and the ratio of taper is at least twenty percent; \n wherein the first transition region and the waist region each have a length of at least 0.5 millimeters; and \n a filtering substance covering at least a portion of the optical fiber taper that attenuate the selected wavelength.
