Abstract: The study of supercontinuum (SC) generation in photonic crystal fiber (PCF) has become an important research subject in fiber communication and photoelectron device development. A review is presented of the experimental and theoretical results of SC generation in silica and nonsilica PCF. For silica PCF, we describe the SC properties in solid-core, hollow-core, and tapered PCF. For nonsilica PCF, the SC properties in some lead silicate glass PCF and tellurite glass PCF are given. To conclude, the applications and prospects of SC generation are discusssed.
