Invited ID: 514 / FS1 S02: 1 Focused Sessions 1: Specialty optical fibers Invited: Room Temperature Mid-infrared Fibre Photoluminescence and Lasing beyond 5 μm in Ce3+ -doped Chalcogenide Glass. 1University of Nottingham, United Kingdom; 2Wroclaw University of Science and Technology, Poland; 3Nottingham Trent University, UK We review here our recent work in achieving mid-infrared (MIR) fibre lasing beyond 5 microns wavelength in Ce3+-doped selenide-chalcogenide fibre, as well as the observed photoluminescence in samples of the same composition but in particulate and bulk glass form as well as unstructured fibre and in the SIF (step index fibre) in which fibre lasing took place. 9:00am - 9:15am
ID: 199 / FS1 S02: 2 Focused Sessions 1: Specialty optical fibers Passive Q-switched Dy:ZBLAN fibre laser at 3.1 um 1Dipartimento di Fisica, Politecnico di Milano, 20133 Milan, Italy; 2School of Physics and Optoelectronics, Xiangtan University, Xiangtan 411105, PR China; 3Istituto di Fotonica e Nanotecnologie, Consiglio Nazionale delle Ricerche, 20133 Milan, Italy The passive Q-switching performance of an in-band pumped Dy-doped fluorozirconate fibre laser emitting around 3.1 um is investigated. Passively Q-switched laser operation is demonstrated employing semiconductor saturable absorber mirrors. Stable operation is achieved, with a minimum pulse duration of 464 ns, a highest repetition frequency of 210 kHz and peak pulse powers up to 3 W. 9:15am - 9:30am
ID: 338 / FS1 S02: 3 Focused Sessions 1: Specialty optical fibers Mitigating the Brillouin strain and temperature cross-sensitivity in heavily GeO2-doped-core optical fibers 1Institut FEMTO-ST, UMR 6174 CNRS, Université de Franche-Comté, Besançon, France; 2Laboratoire Interdisciplinaire Carnot de Bourgogne, UMR 6303 CNRS, Université de Bourgogne (UB), Dijon, France, France We demonstrate an athermal Brillouin strain sensor using heavily GeO2-doped optical fibers. We also report nonlinear evolution of Brillouin temperature sensitivity as a function of wavelength and strong Brillouin gain in these fibers. 9:30am - 9:45am
ID: 282 / FS1 S02: 4 Focused Sessions 1: Specialty optical fibers Towards full mid-infrared supercontinuum generation with tapered chalcogenide-glass rods 1Laboratoire Interdisciplinaire Carnot de Bourgogne, UMR6303 CNRS-Université Bourgogne-Franche-Comté, 9 avenue Alain Savary, 21078 Dijon Cedex, France; 2Research Center for Advanced Photon Technology, Toyota Technological Institute, Nagoya, Japan We experimentally demonstrate that simple tapered Ge-Se-Te glass rods with femtosecond pumping enables efficient multi-octave mid-infrared supercontinuum generation, from 1.7 to 16 µm, while keeping an excellent spatial beam profile. 9:45am - 10:00am
ID: 335 / FS1 S02: 5 TOM 6 Nonlinear and Quantum Optics Intermodal-vectorial four-wave mixing processes involving LP01, LP11, LP02 and LP21 modes of birefringent fibers Wroclaw University of Science and Technology, Poland We present the complete (analytical, numerical and experimental) analysis of intermodal-vectorial four-wave mixings proccesses in birefringent fibers. We analyze phase-matching condition and overlap coefficients to indicate possible processes. Then, we demonstrate multiple four-wave mixing processes in LP01 and LP11 modes numerically and experimentally. Finally, we extend theoretical analysis to account higher order modes: LP02 and LP21. |
