Abstract
A light stripper assembly for dissipating a residual optical pump power carried by a pump light propagating in an optical fiber component is provided. The optical fiber component includes a pump cladding surrounded by an outer cladding, the outer cladding being removed from the optical fiber component along a lengthwise segment thereof. The light stripper assembly includes a pump stripper disposed about the lengthwise segment and a heat-dissipation packaging structure thermally contacting the pump stripper. The pump stripper includes an input guiding region and a stripping region having refractive indices lower and higher than the refractive index at the outermost periphery of the pump cladding, respectively, so that the pump light is at least partially guided inside the pump cladding along the input guiding region and stripped from the pump cladding along the stripping region. The heat-dissipation packaging structure absorbs and dissipates the residual power stripped by the stripping region.
