D-Type Fiber Customization

The NIR-SPF-S-SM-2 SPF series side-polished fiber/D-type fiber (Side Polished Fiber) leverages our comprehensive fiber processing technology. Xiaoxiao Photonics currently offers customized processing services for D-shaped side-polished fibers. With 5 years of unique side-polishing expertise, we can precisely provide large-scale customized services to our clients. Customers only need to specify the fiber type, polishing length, and polishing depth they require.

Product features：High optical surface quality 、Low insertion loss in air 、Supports customization for various compatible fibers 、Different side-polishing depths 、Exposed core length

Application area：Side-polished fiber creates a substrate with definable length and depth through a parallel surface 、Facilitates access to the evanescent field with nearly zero loss 、Guides waveguide properties through the structure and refractive index of the overlay structure 、Achieves time-varying manipulation of propagation by dynamically modifying structure dimensions, refractive index, or absorption 、Fiber optic components and fiber sensing applications
