Abstract :
Dynamic bandgap control in all-solid chalcogenide-tellurite photonic bandgap fiber (PBGF) by the refractive index changes due to the optical Kerr effect is numerically simulated in this paper. The core and the cladding with low index are designed by the tellurite glass TeO2-ZnO-Li2O-Bi2O3, whereas the high-index rods are designed by the chalcogenide glass GeGaSbS. Because all-solid chalcogenide-tellurite PBGF has higher nonlinear refractive index than the conventional silica PBGF, when the high peak power transmits in this fiber, the refractive index will change due to the optical Kerr effect, and so will the bandgap.
