title = "A Cladding Light Stripper with Ultra-low Backscattering",
abstract = "The recent investigation results of our group's on the design and fabrication of a cladding light stripper (CLS) with ultralow backward scattering are reviewed. The relationship between the roughness of the cladding surface and the backscattering of cladding light for the periodically grooved CLS's was investigated using a ray tracing method. A periodically grooved CLS structure with multiple unetched sections of a suitable length was found to efficiently suppress backscattering and verify its efficacy through numerical simulations. A CLS with 8-cm length of an LMA DCF with core and cladding diameters of 20 and 250 μm was fabricated by using a hydrogen fluoride (HF)-free chemical etching technique considering fabrication and environmental safety. It was shown that the stripping efficiency was 98.8\% and the backward beam scattering level was much lower than that of commercially available CLSs.",
