Lasing wavelength dependence of gain-clamped EDFA performance with different optical feedback schemes
T.C Teyo,M.K Leong,Harith Ahmad +2 more
TL;DR: In this article, the performance of gain-clamped erbium-doped fiber amplifier with different optical feedback schemes has been studied as a function of lasing wavelength and an inverse relation of the signal gains with the amplified spontaneous emission spectrum is observed for the entire laser tuning range as a result of the population variation caused by the different strength of the oscillating laser.
Journal ArticleDOI
Single longitudinal mode laser generation using coupled microfiber Mach–Zehnder interferometer filter
Harith Ahmad,Harith Ahmad,K Thambiratnan,M.J. Faruki,Saaidal Razalli Azzuhri,Saaidal Razalli Azzuhri +5 more
TL;DR: In this article, the fabrication and operation of a single longitudinal mode (SLM) laser using a compact coupled microfiber Mach-Zehnder interferometer (CM-MZI) in an erbium doped fiber (EDF) laser cavity is demonstrated.
Journal ArticleDOI
Wide-range in-fibre Fabry-Perot resonator for ultrasonic sensing
Md. Rajibul Islam,Muhammad Mahmood Ali,Man-Hong Lai,Kok-Sing Lim,Dinusha Serandi Gunawardena,V. R. Machavaram,Harith Ahmad +6 more
TL;DR: In this article, a short cavity fiber Fabry-Perot resonator (FPR) was used for the detection of ultrasonic waves propagating through a solid medium over a frequency range of 1 kHz-10 MHz.
Journal ArticleDOI
Acrylate polymer coated side-polished fiber with graphene oxide nanoparticles for ultrafast fiber laser operation
TL;DR: In this article, a mode-locked fiber laser with a side-polished fiber coated with graphene oxide nanoparticles as a saturable absorber (SA) is proposed and demonstrated.
Journal ArticleDOI
Tunable and switchable Brillouin multi-wavelength thulium fluoride fiber laser in S/S+ band region
TL;DR: In this paper, a multi-wavelength fiber laser with a channel spacing of 0.17nm operating in the S-band region is proposed and demonstrated, which exploits the stimulated Brillouin scattering (SBS) effect to generate the desired output using a 6.9 km long dispersion shifted fiber.
