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.
