Dual‐wavelength passively Q‐switched Erbium Ytterbium codoped fiber laser based on a nonlinear polarization rotation technique

M B S Sabran, +4 more
- 01 Mar 2015 - 
TL;DR: In this paper, a dual-wavelength Erbium ytterbium codoped fiber laser (EYDFL) operating at 1543.3 and 1545.4 nm using a nonlinear polarization rotation (NPR) technique was reported.
Journal ArticleDOI

Generation of four-wave mixing with nonlinear Vanadium-carbide (V2C)-deposited side-polished fiber (SPF) in 1.5- and 2.0-µm wavelength operation

Rubem de Mesquita Valadares, +8 more
- 01 Jan 2022 - 
TL;DR: In this paper, the use of V2C-deposited SPF as a nonlinear device for the generation of four-wave mixing (FWM) effect in 1.5- and 2.0-µm wavelength operation was reported.
Journal ArticleDOI

Broadband tuning in a passively Q-switched erbium doped fiber laser (EDFL) via multiwall carbon nanotubes/polyvinyl alcohol (MWCNT/PVA) saturable absorber

Harith Ahmad, +5 more
- 15 Apr 2016 - 
TL;DR: An MWCNT/PVA-based Q-switched erbium-doped fiber laser (EDFL) that uses a tunable bandpass filter (TBPF) as the wavelength tuning and filtering mechanism to achieve a broadband tuning range is proposed and demonstrated in this paper.

Design of multimode tapered fibre sensor for glucose detection

Moh. Yasin, +5 more
TL;DR: From this work, the tapered PMM fibre performs better in terms of its linearity, and provides a reliable calibration graph of glucose concentration against output signal, and has a better sensitivity, error and a better resolution but a lesser degree of linearity.
Journal ArticleDOI

Demonstration of microfiber hybrid Mach–Zehnder and knot resonator structure

A. Sulaiman, +6 more
- 01 Jan 2013 - 
TL;DR: In this paper, a microfiber hybrid structure consisting of a micro-fiber knot resonator (MKR) and a micro fiber Mach-Zehnder interferometer (MMZI) was demonstrated.
