ABSTRACT
Photonic crystal fibers are microstructured optical fibers that have gained significant scientific interest over the past several years. They are widely used in various sensing applications, such as biosensors, supercontinuum sources, all-optical nonlinear devices, and so on. Their unique morphology, flexible light-guiding properties, and exceptional ability to host optical materials make them an outstanding candidate in photonics. Chalcogenide glasses are excellent infrared optical materials for active and passive photonic applications due to their remarkable optical, thermal, and electronic properties. Incorporating photonic crystal fibers with chalcogenide glasses opens a broad window into realizing integrated photonic devices. This chapter introduces photonic crystal fibers and their guiding mechanisms, and chalcogenide glass-integrated photonic crystal fibers, and their applications.
