An optical parametric amplifier has been demonstrated by using a 3-m-long tellurite microstructured fiber as the gain medium. Due to the highly nonlinear property, a maximal peak gain of 90.2 dB has been achieved in the S band.
A hybrid AsSe2-As2S5 microstructured optical fiber is fabricated by the rod-in-tube drawing technique. Soliton self-frequency shift with a soliton center wavelength from ∼2.986 to 3.419 μm is observed at the pump wavelength of ∼2.8 μm.
We demonstrate the supercontinuum generation in an As2Se5 microstructured optical fiber experimentally. The SC bandwidth of 4280 nm wider than two octaves covering from 1370 to 5650 nm is obtained in 4.8 cm long fiber.
A new way to suppress stimulated Brillouin scattering (SBS) by using an all-solid chalcogenide-tellurite photonic bandgap fiber (CT PBGF) is presented in the paper. The compositions of the chalcogenide and the tellurite glass are As2Se3 and TeO2-ZnO-Li2O-Bi2O3. Light and acoustic wave are confined in the fiber by photonic bandgap (PBG) and acoustic bandgap (ABG) mechanism, respectively [1].
A simple all-solid tellurite microstructured optical fiber which has only one layer of high-index rods is proposed and fabricated. The core and cladding are made from the TeO2-ZnO-Na2O-La2O3 glass, and the high-index rods are made from the TeO2-Li2O-WO3-MoO3-Nb2O5 glass.
