Ytterbium-Phosphate Glass for Microstructured Fiber Laser
Autor: Ryszard Stępień, Marcin Franczyk, Dariusz Pysz, Ireneusz Kujawa, Mariusz Klimczak, Ryszard Buczyński
Publikováno v: Materials, Vol 7, Iss 6, Pp 4723-4738 (2014)
In the paper, we report on the development of a synthesis and melting method of phosphate glasses designed for active microstructured fiber manufacturing. Non-doped glass synthesized in a P2O5-Al2O3-BaO-ZnO-MgO-Na2O oxide system served as the matrix

Development of Dispersion-Optimized Photonic Crystal Fibers Based on Heavy Metal Oxide Glasses for Broadband Infrared Supercontinuum Generation with Fiber Lasers
Autor: Grzegorz Stępniewski, Jacek Pniewski, Dariusz Pysz, Jarosław Cimek, Ryszard Stępień, Mariusz Klimczak, Ryszard Buczyński
Publikováno v: Sensors, Vol 18, Iss 12, p 4127 (2018)
In this work a photonic crystal fiber made of a heavy metal oxide glass with optimized dispersion profile is proposed for supercontinuum generation in a broad range of wavelengths in the near-infrared, when pumped by a mode-locked fiber-based laser.

Autor: Hue Thi Nguyen, Rafal Kasztelanic, Adam Filipkowski, Dariusz Pysz, Hieu Van Le, Ryszard Stepien, Takashige Omatsu, Wieslaw Krolikowski, Ryszard Buczynski
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-11 (2023)
Abstract We developed a new kind of compact flat-surface nanostructured gradient index vortex phase mask, for the effective generation of optical vortex beams in broadband infrared wavelength range. A low-cost nanotechnological material method was em

Fused silica photonic crystal fiber with heavily germanium doped microinclusion in the core dedicated to couple, guide and control LP
Autor: Tomasz, Stefaniuk, Grzegorz, Stępniewski, Dariusz, Pysz, Ryszard, Stępień, Ryszard, Buczyński
Publikováno v: Optics express. 26(17)
We report on modeling, development, and optical characterization of fused silica photonic crystal fiber with germanium doped microinclusion placed in the middle of the core. The fiber is designed to efficiently couple and guide LP
