Journal ArticleDOI
Titanium Dioxide (TiO2) film as a new saturable absorber for generating mode-locked Thulium-Holmium doped all-fiber laser
Muhammad Farid Mohd Rusdi,Anas Abdul Latiff,Mukul Chandra Paul,Shyamal Das,Anirban Dhar,Harith Ahmad,Sulaiman Wadi Harun +6 more
TL;DR: In this paper, a mode-locked thulium-holmium doped fiber laser (THDFL) was demonstrated using Titanium Dioxide (TiO 2 ) film as a saturable absorber.
Journal ArticleDOI
Wideband EDFA Based on Erbium Doped Crystalline Zirconia Yttria Alumino Silicate Fiber
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: In this article, a wideband erbium-doped fiber amplifier (EDFA) is demonstrated using an Erbiumdoped zirconia fiber as the gain medium.
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
Ytterbium-sensitized Thulium-doped fiber laser in the near-IR with 980 nm pumping.
TL;DR: The use of an unidirectional auxiliary pump at approximately 1600 nm in conjunction with a 980 nm primary pump for Ytterbium-sensitized-Thulium-doped single mode silica fiber (YTDF) is found to be very effective to activate the most significant resonance energy transfer from Yb(3+) to Tm(3+), in order to obtain significant emission in the near-infrared.
Journal ArticleDOI
Titanium dioxide doped fiber as a new saturable absorber for generating mode-locked erbium doped fiber laser
P. Harshavardhan Reddy,P. Harshavardhan Reddy,M.F.A. Rahman,M.F.A. Rahman,Mukul Chandra Paul,Anas Abdul Latiff,Anas Abdul Latiff,A.H.A. Rosol,Shyamal Das,Anirban Dhar,Shyamal Kumar Bhadra,Kaharudin Dimyati,Sulaiman Wadi Harun +12 more
TL;DR: In this article, the authors used titanium dioxide doped fiber (TiO2DF) as a passive saturable absorber (SA) in generating stable and self-starting mode-locked pulse laser.
