Patent ID: 8885993

Claim:
A light stripper assembly for dissipating a residual optical pump power carried by a pump light propagating an optical fiber component, the optical fiber component comprising a core, a pump cladding guiding the pump light thereinside and surrounding the core, and an outer cladding surrounding the pump cladding, the outer cladding being removed from the optical fiber component along a lengthwise segment thereof, the light stripper assembly comprising: an input guiding region made of a material having a refractive index lower than a refractive index of an outermost periphery of the pump cladding, so that the pump light continues to be guided inside the pump cladding along a portion of the pump stripper; and a stripping region adjacent to and downstream of the input guiding region, the stripping region being made of a material having a refractive index higher than the refractive index of the outermost periphery of the pump cladding, the stripping region stripping the residual optical pump power from the pump cladding; and a heat-dissipation packaging structure in thermal contact with the pump stripper, the heat-dissipation packaging structure in thermal contact with the pump stripper, the heat-dissipation packaging structure absorbing and dissipating the residual optical pump power stripped by the stripping region of the pump stripper, wherein the material of each of the input guiding region and the stripping region of the pump stripper is a heat-resistant material adapted to withstand heat generated upon stripping and absorption of the residual optical pump power from the pump cladding, wherein the material of each of the input guiding region and the stripping region of the pump stripper is adapted to withstand exposure to temperatures of at least 200° C.
