Journal ArticleDOI
Active and passive chalcogenide glass optical fibers for IR applications: a review
TL;DR: In this article, the authors asserted that the research and development of chalcogenide glasses will grow in the foreseeable future, especially with respect to improvements in the optical quality of the fibers and the performance of the fiber in existing and future applications.
Journal ArticleDOI
Highly nonlinear As-S-Se glasses for all-optical switching.
J. M. Harbold,Fatih Omer Ilday,Frank W. Wise,Jasbinder S. Sanghera,V.Q. Nguyen,Leslie Brandon Shaw,Ishwar D. Aggarwal +6 more
TL;DR: A series of chalcogenide glasses from the As-S-Se system that is designed to have strong nonlinearities are synthesized and measurements reveal that many of these glasses offer optical Kerr non linearities greater than 400 times that of fused silica.
Journal ArticleDOI
Large Raman gain and nonlinear phase shifts in high-purity As 2 Se 3 chalcogenide fibers
Richart Elliott Slusher,Gadi Lenz,Juan Hodelin,Jasbinder S. Sanghera,L. Brandon Shaw,Ishwar D. Aggarwal +5 more
TL;DR: In this paper, the third-order Kerr nonlinearities and Raman gain were studied experimentally in high-purity As2Se3 optical fibers for wavelengths near 1.55 μm.
Journal ArticleDOI
Large Kerr effect in bulk Se-based chalcogenide glasses.
Gadi Lenz,J. Zimmermann,Takuro Katsufuji,M.E. Lines,Harold Y. Hwang,Stefan Spälter,Richard E. Slusher,Sang-Wook Cheong,Jas S. Sanghera,Ishwar D. Aggarwal +9 more
TL;DR: A number of compounds with a Kerr nonlinearity hundreds of times larger than silica are found, making them excellent candidates for ultrafast all-optical devices.
Journal ArticleDOI
Chalcogenide Glass-Fiber-Based Mid-IR Sources and Applications
TL;DR: In this article, the authors review rare-earth-doped chalcogenide fiber for mid-and long-wave IR lasers, and highly nonlinear chalgogenide fibers and photonic crystal fiber for wavelength conversion in the mid and longwave IR.
