Journal ArticleDOI
Dual-wavelength tunable fibre laser with a 15-dBm peak power
Amirah Abdul Latif,Noor Azura Awang,Mohd Zamani Zulkifli,Sulaiman Wadi Harun,Z.A. Ghani,Harith Ahmad +5 more
TL;DR: In this article, a high-power dual-wavelength tunable fiber laser (HP-DWTFL) operating in the C-band at wavelengths from 1536.7 nm to 1548.6 nm is proposed and demonstrated.
Journal ArticleDOI
Morphology effect of zinc oxide on nonlinear optical properties for soliton mode-locked fiber laser
TL;DR: In this article , the effect of morphology on the nonlinear optical properties of a mode-locked pulsed fiber laser was further investigated, and the results of this work could give a valuable guideline for selecting the appropriate nanomaterial-based SA for various photonics applications.
Journal ArticleDOI
On comparison of the temperature sensitivity of SU-8-based triple-arm MZI against straight rib optical waveguides patterned on silicon wafer
TL;DR: In this article, the temperature sensitivity of SU-8-based triple-arm Mach-Zehnder interferometer (MZI) and straight waveguide is investigated. But, the results of the experiments were limited to the same heating source and under the same environmental conditions.
Journal ArticleDOI
A novel wideband erbium-doped fiber amplifier design
TL;DR: In this paper, a wideband erbium-doped fiber amplifier utilizing a bidirectional amplification of conventional and long-wavelength band signals is presented Amplification of a four-channel wavelength-division multiplexing system (two channels for each band) with an average gain of 20 dB and a noise figure less than 75 dB.
Journal ArticleDOI
