Thermal Diffusion Expansion Fiber Core Custom Processing, Core Diameter 20um

NIR-TEC-30-9-SA TEC (Thermally-diffused Expanded Core Fiber) fiber technology, with the mode field diameter at the end of the thermally-expanded fiber core. This can be used in commercial SI-SMF (Single-Mode Fiber). The mode field diameter increases by one or three times at the fiber end, altering the refractive index distribution and reducing the numerical aperture. The larger the axial and gap displacement tolerances, the smaller the coupling loss. Small variations in cladding diameter can be compensated by inserting a metal sleeve and installing a connector (as shown in the figure below).

Product features：High optical surface quality、 High control precision、 Low insertion loss

Application area：Silicon photonics integration technology、 Optical waveguide coupling、 Optical equipment manufacturing、 Testing tools
