Abstract:
In order to take advantage of the 1.33-µm emission from 4F3/2→4I13/2 transition of Nd3+ ions to realize many potential applications in this telecommunication band, it is important to filter out the intense 1.06-µm emission from the 4F3/2→4I11/2 transition. In this work, a new tellurite all-solid photonic bandgap fiber with double cladding layer was proposed. In addition, 8 high-index rods and an Nd3+-doped core were arranged in a horizontal line and located in the center of the fiber. Numerical calculation was carried out to study the properties of the propagation modes at 0.8, 1.06 and 1.33 µm. By controlling the diameters of the core and high-index rods, it is possible to reduce the intensity of the 1.06-µm light, but maintain the intensity of the lights at 0.8 and 1.33 µm when they propagate in the fiber core.
