“…3. The As 3d orbital peak fitted well with two sub-peaks (1-1 0 and 2-2 0 ), from whose positions and separations [5] we can deduce the bonding configurations. Peak 1-1 0 resolves to an As atom surrounded by three sulphurs, and 2-2 0 to an As atom with two S and one As atom.…”

“…The model takes into account the experimental chromatic dispersion and losses. It also includes Kerr, nonlinear (two-photon) absorption, self-steepening and Raman terms based on the previous studies of As 2 S 3 glass [13,24,37,38]. Numerical predictions (black lines and crosses) are compared to experimental spectra in Fig.…”

Abstract:We report the fabrication and characterization of the first guiding chalcogenide As 2 S 3 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. C.

High-index-contrast, compact microdisk resonators in thermally evaporated As 2 S 3 and Ge 17 Sb 12 S 71 chalcogenide glass films are designed, fabricated using standard UV lithography and characterized. Our pulley coupler configuration demonstrates coupling of the resonators to monolithically integrated photonic wire waveguides without resorting to demanding fine-line lithography. Microdisk resonators in As 2 S 3 support whisperinggallery-mode with cavity quality factors (Q) exceeding 2 × 10 5 , the highest Q value reported in resonator structures in chalcogenide glasses to the best of our knowledge. We have successfully demonstrated a lab-on-a-chip prototype sensor device with the integration of our resonator with planar microfluidic systems. The sensor shows a refractive index sensitivity of 182 nm/RIU (refractive index unit) and a wavelength resolution of 0.1 pm through resonant peak fit. This corresponds to a refractive index detection limit of 8 × 10 -7 RIU at 1550 nm wavelength, which could be further improved
