Strong infrared spectral broadening in low-loss As-S chalcogenide suspended core microstructured optical fibers

Abstract : We report the fabrication and characterization of the first guiding chalcogenide As2S3 microstructured optical fibers (MOFs) with a suspended core. At 1.55 µm, the measured losses are approximately 0.7 dB/m or 0.35 dB/m according to the MOF core size. The fibers have been designed to present a zero dispersion wavelength (ZDW) around 2 µm. By pumping the fibers at 1.55 µm, strong spectral broadenings are obtained in both 1.8 and 45-m-long fibers by using a picosecond fiber laser.
