Supercontinuum from Zr-EDF using Zr-EDF mode-locked fiber laser
Harith Ahmad,Noor Azura Awang,Noor Azura Awang,Mohd Zamani Zulkifli,Kavintheran Thambiratnam,Mukul Chandra Paul,Shyamal Das,Sulaiman Wadi Harun +7 more
TL;DR: In this article, the authors proposed and demonstrated the generation of a supercontinuum (SC) spectrum from a 10 m long silica fiber co-doped with zirconia-yttria-alumino and erbium (Zr-EDF) as a nonlinear medium.
Journal ArticleDOI
Note: Fabrication of tapered fibre tip using mechanical polishing method
TL;DR: A two-step hybrid fabrication method combining the proposed polishing method with chemical etching method to increase the possible fibre tip cone angles achievable by chemical etch method is presented.
Journal ArticleDOI
Effects of different Raman pumping schemes on stimulated Brillouin scattering in a linear cavity
Mohammadreza Rezazadeh Shirazi,Mozhgun Biglary,Sulaiman Wadi Harun,Kavintheran Thambiratnam,Harith Ahmad +4 more
TL;DR: Surprisingly, it is revealed that the SBS threshold reduction depends strongly and solely on Raman gain and it is independent of the Raman pumping schemes.
Journal ArticleDOI
Multi-wavelength Brillouin-Raman fiber laser generation assisted by multiple four-wave mixing processes in a ring cavity
TL;DR: In this paper, a multi-wavelength Brillouin?Raman fiber laser (MBRFL) is generated by using a 7.7?km long dispersion compensating fiber which acts as both the BrillouIN and Raman gain media.
Journal ArticleDOI
S-band multiwavelength Brillouin Raman Fiber Laser
TL;DR: In this article, the S-band Brillouin-Raman fiber laser (BRFL) was proposed and demonstrated using a linear cavity configuration and two 1425-nm, 380mW pumped Raman fiber Amplifiers (RFAs).
