We present an all-solid tellurite-phosphate photonic bandgap fiber (PBGF) with high-index rods in the cladding. The low-index background material is phosphate glass (PZNK) and the high-index rods are made of tellurite glass (TZLB). The all-solid tellurite-phosphate PBGF has three bandgaps and the first one is wide in frequency. It is easier to draw than the silicon PBGF due to the phosphate glass has lower fiber-drawing temperature. It can be widely used in the photoelectron field, compact nonlinear devices and devices which work in the mid-infrared range, such as wavelength filter, phase-locked high-power lasers, fiber sensors in the mid-infrared for gases detecting, etc.
