Journal ArticleDOI
Performance comparison of Zr-based and Bi-based erbium-doped fiber amplifiers.
Mukul Chandra Paul,Sulaiman Wadi Harun,N.A.D. Huri,A Hamzah,Shyamal Das,Mrinmay Pal,Shyamal Kumar Bhadra,Harith Ahmad,S. Yoo,M.P. Kalita,Alexander J. Boyland,Jayanta K. Sahu +11 more
TL;DR: It was found that a zirconia-based erbium-doped fiber amplifier can achieve even better flat-gain value and bandwidth as well as lower noise figure than the conventional Bi-EDFA.
Journal ArticleDOI
Reply to comment on “Photodarkening in Yb-doped aluminosilicate fibers induced by 488 nm irradiation”
S. Yoo,Chandrajit Basu,Alexander J. Boyland,Collin Sones,Johan Nilsson,Jayanta K. Sahu,David N. Payne +6 more
TL;DR: The photodarkening of Yb-doped aluminosilicate fibers by continuous wave 488 nm irradiation could be significantly reduced, which is attributed to a smaller number of ODCs following oxygen loading.
Journal ArticleDOI
Electro-optically controlled beam deflection for grazing incidence geometry on a domain-engineered interface in LiNbO3
TL;DR: In this article, an analysis on the electro-optically induced beam deflection experienced by light traversing an interface between two anti-parallel domains in a sample of LiNbO3 is presented.
Journal ArticleDOI
Broadly tunable single-frequency cw mid-infrared source with milliwatt-level output based on difference-frequency generation in orientation-patterned GaAs.
Sergey Vasilyev,Stephan Schiller,Alexander Nevsky,Arnaud Grisard,D. Faye,Eric Lallier,Zhaowei Zhang,Alexander J. Boyland,Jayanta K. Sahu,Morten Ibsen,W.A. Clarkson +10 more
TL;DR: A narrow-linewidth mid-IR source based on difference-frequency generation of an amplified 1.5 microm diode laser and a cw Tm-doped fiber laser in orientation-patterned (OP) GaAs has been developed and evaluated for spectroscopic applications.
Journal ArticleDOI
Linearly polarized ytterbium-doped fiber laser in a pedestal design with aluminosilicate inner cladding
TL;DR: Ytterbium-doped polarization-maintaining fiber in a pedestal geometry is demonstrated using MCVD and a novel in-situ doping technique in this article, where aluminosilicate pedestal layers minimize the thermal expansion mismatch against the silica outer cladding and permit complete freedom of location for the stress-applying parts in the fiber.
