Ultrabroadband and coherent mid-infrared supercontinuum generation in all-normal dispersion Te-based chalcogenide all-solid microstructured fiber

We report an ultrabroadband supercontinuum (SC) generation with high coherence property in all-normal-dispersion (ANDi) Te-based chalcogenide all-solid microstructured optical fiber (AS-MOF). The fiber was fabricated using a rod-in-tube method that presents four ${{\rm As}_2}{{\rm S}_3}$As2S3 glass rods selected as low refractive index material ($n = {2.4}$n=2.4) embedded in a ${{\rm Ge}_{20}}{{\rm As}_{20}}{{\rm Se}_{20}}{{\rm Te}_{40}}$Ge20As20Se20Te40 glass matrix ($n = {3.1}$n=3.1). The highly symmetrical four-hole MOF preform was fabricated through the computerized numerical control precision mechanical drilling method. By engineering the structure of the fiber, we determined an ANDi characteristic in the range of 2–13.5 µm when the core diameter of the fiber was $ \le\!{10\,\,\unicode{x00B5}{\rm m}}$≤10µm. Under pumping at 5 µm, a highly coherent SC generation in the range of 2–13.2 µm was generated in a 16-cm-long AS-MOF with core diameter of 9.8 µm.
