Compared with silica glass, chalcogenide glasses possess some unique advantages, such as high refractive indices (2.0～3.5), low photon energies (lower than 350 cm-1), tailorable compositions, and large infrared transmission window (from 1.0 to 20 mm). As a novel mid-infrared photonic crystal fiber (PCF), chalcogenide glass PCFs have attracted many attention recently. We review the research progress of chalcogenide glass PCFs, in terms of the glass composition design, structure simulation, fiber fabrication, reduction of transmission loss and their special properties, e.g., dispersion properties and high optical nonlinearity. Their potential applications and development prospects are also discussed.
