Fiber Cladding Mode Stripper

Presented and characterized are an optimized cladding mode stripper design that increases the cladding light loss with a minimal device length and manufacturing time. this design reduces the heat generation by improving the heat distribution along the device. We demonstrate a cladding mode stripper written on a 400 μm fiber with cladding light loss of 20 dB with less than 0.02 dB loss in the core and minimal heating of the fiber and coating. The manufacturing process of the designed component is fully automated and takes less than three minutes with a very high throughput yield.
