Nor Farhah Razak, +5 more
- 01 Jan 2015 - 
TL;DR: In this paper, a single longitudinal mode (SLM) erbium-doped fiber (EDF) laser operation using a commercialized ultra-narrow bandwidth optical filter has been demonstrated.
Journal ArticleDOI

The influence of aqueous sodium dodecyl sulphate solution in the photoresponsivity of nitrogen doped graphene oxide photodetector

Harith Ahmad, +1 more
- 01 Nov 2017 - 
TL;DR: In this paper, the influence of sodium dodecyl sulphate (SDS) solution in nitrogen doped graphene oxide (N-GO) is studied based on the photoresponsivity behavior.
Journal ArticleDOI

Flat-gain wide-band erbium doped fiber amplifier by combining two difference doped fibers

Belal Ahmed Hamida, +6 more
- 12 Mar 2015 - 
TL;DR: In this article, a combination of newly developed Erbium Zirconia co-doped fiber (Zr-EDF) and the commercial silica-based EDF as the gain medium was used to achieve a flat gain of 15 dB with a gain variation of less than 0.5 dB.
Journal ArticleDOI

Dispersion-engineered silicon nitride waveguides for mid-infrared supercontinuum generation covering the wavelength range 0.8─6.5 μm

Harith Ahmad, +3 more
- 18 Jan 2019 - 
TL;DR: In this paper, the authors numerically demonstrate the generation of a mid-infrared supercontinuum (SC) through the design of an on-chip complementary metal oxide semiconductor (CMOS) compatible 10mm-long air-clad rectangular waveguide made using stoichiometric silicon nitride (Si 3 N 4 ) as the core and MgF 2 glass as its lower cladding.
Journal ArticleDOI
