Document Type and Number:
WIPO Patent Application WO/2024/078407
Kind Code:
A1
Abstract:
An optical fiber mode stripper, an optical fiber mode stripper preparation method, and a laser. The optical fiber mode stripper comprises: an optical fiber (100) and a filler (200); the optical fiber (100) is provided with a waveguide damage area (140) extending along the length direction of the optical fiber; the optical fiber in the waveguide damage area (140) comprises a fiber core (110) and a cladding layer (120); the cladding layer (120) has provided thereon a plurality of recessed structures (150) arranged at intervals along the length direction of the optical fiber and/or arranged at intervals around the circumference of the cladding layer; and the filler (200) fills the recessed structures (150), and the refractive index of the filler (200) is greater than the refractive index of the cladding layer (120).
