1.7–18?μm mid-infrared supercontinuum generation in a dispersion-engineered step-index chalcogenide fiber

摘要

We demonstrate 1.7–18?μm mid-infrared coherent supercontinuum generation by means of the full transmission window of a unique dispersion-engineered step-index Ge-Se-Te fiber. Our study thus opens the entire molecular fingerprint region to future chalcogenide fiber platforms.
