Abstract
A cladding light stripper may include a double-clad optical fiber having a core for guiding signal light, an inner cladding surrounding the core, and an outer cladding surrounding the inner cladding. The optical fiber may include a stripped portion forming an exposed section. The exposed section may include a plurality of spirally-arranged transversal notches disposed along the optical fiber to enable light to escape the inner cladding upon impinging on the plurality of notches. A circumferential segment of the optical fiber may include a single notch of the plurality of notches. Each of the plurality of notches may have a depth of only a partial distance to the core.
