Development of optical fiber technology in Poland 2015
The paper is a digest of works presented during the XVIth National Symposium on Optical Fibres and Their Applications. The Symposium is organized since 1976. OFTA 2015 was organized by Optical Fibre Laboratory of the Faculty of Chemistry at University of Maria Curie Skłodowska, and Institute of Electronics and Information Technology of Lublin University of Technology, in Nałęczów on 22-25 September 2015. The meeting has gathered around 120 participants who presented 85 research and technical papers. The Symposium organized every 18 months is a good portrait of optical fibre technology development in Poland at university laboratories, governmental institutes, company R&D laboratories, etc. Topical tracks of the Symposium were: optical and photonic materials, technology of classical, tailored and structural photonic optical fibres, light propagation physics in optical fibres, passive and active optical fibre components, optical fibre sensors, passive and active optical fibre networks, optical fibre amplifiers and lasers, optical fibre network issues: modulation, architectures, economy, etc.
Laser technology 2012
Laser technology research community in this country and in this region is concentrated mainly at universities. A periodic symposium gathers this community and invited guests from this geographical region to summarize the current achievements. The 2012 Symposium summarized research and technical achievements done during the period of 2010- 2012. The main developments are focused in such areas like: semiconductor lasers, optical fiber amplifiers and lasers, and applications in optical fiber communications, optical fiber sensory networks, medicine, environment monitoring and protection, as well as safety and security.
A numerical study on liquid ring motion and fragmentation for the initial process of liquid explosive dispersal
For the explosive dispersal on liquid fuel of FAE technique, the expansion of gaseous detonation products, axisymmetric radial extension and fragmentation of a liquid ring were analyzed, then corresponding models were established. By those models coupled, the numerical simulation on motion and fragmentation of the liquid ring exerted by strong action was carried out. The results computed show that the models established are feasible, and present study can offer initial conditions for the numerical simulation on the process of liquid secondary breakup and gas-liquid mixing.
