Abstract

A novel seven-core multicore tellurite fiber is proposed and fabricated in the paper. Each core with high index is made of 70TeO₂-8Li₂O-19WO₃-1MoO₃-2Nb₂O₅ (mol%) glass. The background with low index is made of 70TeO₂-20ZnO-5Na₂O-5La₂O₃ (mol%) glass. Compared with the single-core tellurite fiber, this fiber has novel chromatic dispersion with two zero-dispersion wavelengths at 1.86 μm and 2.16 μm. The spatial interference fringes generated in the different cores of the fiber are obvious.
