AI Technical Summary
Technical Problem
The existing suspension core optical fiber has complex structure, high production cost, high loss and narrow dispersion range.
Method used
A terahertz suspension core optical fiber is designed, adopting the revised total internal reflection principle, and the core and cladding are formed through the special structure of multiple Class I dielectric tubes and Class II dielectric tubes. The effective refractive index of the fiber core is greater than the effective refractive index of the cladding.
Benefits of technology
It achieves extremely low loss and wide and flat dispersion characteristics, reduces absorption losses, and improves the stability and deformation resistance of the optical fiber.

Abstract
The invention provides a terahertz suspension core optical fiber, which belongs to the technical field of optical fibers and comprises an outer sleeve, a plurality of I-type dielectric tubes and a plurality of II-type dielectric tubes with the same number as the I-type dielectric tubes, wherein the plurality of I-type medium pipes are arranged in the outer sleeve, and each I-type medium pipe is tangent to the outer sleeve; the multiple II-type medium pipes are arranged in the outer sleeve, and one II-type medium pipe is arranged on the outer wall of each I-type medium pipe in a tangent mode; based on a modified total internal reflection principle, the dependence of a traditional suspension core optical fiber on a thin arm in structure is avoided; the simple optical fiber structure with all structural units being circular boundaries has more prominent advantages in optical fiber manufacturing. The hollow porous structure can ensure that most of energy in the mode is distributed in the air, so that the absorption loss is effectively reduced.
