An efficient and low noise Gain-Clamped Double-Pass L-Band EDFA
Sulaiman Wadi Harun,Harith Ahmad +1 more
TL;DR: A highly efficient and low noise gain-clamped long-wavelength-band erbium-doped fiber amplifier (L-band EDFA) is demonstrated using a ring laser in double-pass system.
Journal ArticleDOI
Generation of four-wave mixing in molybdenum ditelluride (MoTe2)-deposited side-polished fibre
Harith Ahmad,Muhammad Khairol Annuar Zaini,A.A. Kamely,M.Z. Samion,Mohammad Faizal Ismail,Kok-Sing Lim,A.K. Zamzuri,K. Thambiratnam +7 more
TL;DR: In this article, the effect of four-wave mixing (FWM) in MoTe2 deposited on a side-polished fiber (SPF) was reported, with a nonlinear coefficient of 17.368 W−1 km−1 at 1550 nm.
Journal ArticleDOI
Q-switched pulse generation from an all-f iber distributed Bragg reflector laser using graphene as saturable absorber
TL;DR: In this article, a Q-switched distributed Bragg reflector fiber laser using a graphene passive saturable absorber is proposed in a cavity consisting of a fiber Bragg grating and Faraday rotator mirror as end mirrors, together with a highly doped erbium-doped fiber as a gain source.
Journal ArticleDOI
A Polyaniline-Coated Integrated Microfiber Resonator for UV Detection
Kok-Sing Lim,Yeong-Siang Chiam,Sook-Wai Phang,Wu Yi Chong,Chang Hong Pua,A. Z. Zulkifli,I. Ganesan,Sulaiman Wadi Harun,Harith Ahmad +8 more
TL;DR: In this article, a thin layer of polyaniline (PAni) is deposited on a 1mm-diameter microfiber ring resonator-the sensing region of the detector, and red shift is observed in the output spectrum when PAni is irradiated with a UV light with a peak wavelength at 365 nm.
Journal ArticleDOI
Generation of femtosecond soliton tweezers using a half-panda system for modeling the trapping of a human red blood cell
Iraj Sadegh Amiri,Sayed Ehsan Alavi,M. R. K. Soltanian,Abu Sahmah Mohd. Supa'at,Norsheila Fisal,Harith Ahmad +5 more
TL;DR: In this paper, a modified add/drop multiplexer system, known as half-panda ring resonator, was proposed for human blood cells trapping and deployment during investigations on deformation and vibration behavior of biological cells.
