A Tm-Bi Co-Doped Fiber Laser with Dual Pumping Operation
N. Saidin,Sulaiman Wadi Harun,S S A Damanhuri,S. M. M. Ali,Harith Ahmad,A Halder,Mukul Chandra Paul,Shyamal Das,Mrinmay Pal,Shyamal Kumar Bhadra +9 more
TL;DR: In this paper, the authors demonstrate an efficient fiber laser operating at 1901.6 nm using a newly developed thulium bismuth co-doped fiber (TBF) with dual pumping at 792 nm and 1552 nm.
Journal ArticleDOI
Measurement of fiber non-linearity based on four-wave mixing with an ASE source
TL;DR: In this article, a new four-wave mixing scheme to measure the nonlinear coefficient of fibers is introduced, which avoids the Brillouin backscattering, rendering this a more accurate method to determine fiber nonlinearities than conventional coherent FWM systems.
Journal ArticleDOI
Extraction of a single Stokes line from a Brillouin fibre laser using a silicon oxynitride microring filter
Mohd Zamani Zulkifli,Wu Yi Chong,Andrea Melloni,Francesco Morichetti,Sulaiman Wadi Harun,Harith Ahmad +5 more
TL;DR: In this article, a single channel Brillouin Stokes line generated by pumping a length of single mode fiber is demonstrated using a silicon oxynitride microring resonator.
Journal Article
Soliton pulse generation using a swcntspolyvinyl alcohol thin film based passive saturable absorber
TL;DR: In this paper, a single-walled carbon nanotubes (SWCNTs) polymer composite based thin film passive saturable absorber was demonstrated using a simple solution casting approach.
Journal ArticleDOI
Multi- and dual-wavelength Thulium-doped fluoride fiber laser assisted by four-wave mixing in S-band region
TL;DR: In this article, the Sagnac loop was used as a comb-like wavelength filter, while a 10-km long dispersion compensating fiber was utilized to induce the four-wave mixing (FWM) effect in the cavity.
