Gain improvement in a dual-stage S-band EDFA by filtration of forward C-band ASE by Harun, Sulaiman Wadi, Zulkifli, Mohd Zamani, Tamjis, Mohamad Rom, Ahmad, Harith

“…Gain improvement in a dual-stage S-band erbium-doped fiber amplifier (S-band EDFA) is demonstrated using a broadband fiber Bragg grating (FBG) operating in the conventional-band (C-band) region or a C-band/S-band wavelength division multiplexing (WDM) coupler which filters out the forward C-band amplified spontaneous emission (ASE) in the amplifier system, thus increasing the population inversion in the S-band region. …”

Self-Calibrating Automated Characterization System for Depressed Cladding EDFA Applications Using LabVIEW Software With GPIB by Zulkifli, Mohd Zamani, Harun, Sulaiman Wadi, Thambiratnam, Kavintheran, Ahmad, Harith

Bidirectional S-band continuous wave operation in a depressed-cladding erbium doped fiber amplifier by Ahmad, Harith, Zulkifli, Mohd Zamani, Latif, Amirah Abdul, Thambiratnam, Kavintheran, Harun, Sulaiman Wadi

“…In this paper we propose and characterize a bi-directional Depressed-Cladding Erbium Doped Fibre Amplifier (DC-EDFA) for Continuous Wave (CW) S-band operation. …”

Switchable semiconductor optical fiber laser incorporating AWG and broadband FBG with high SMSR by Ahmad, Harith, Zulkifli, Mohd Zamani, Thambiratnam, Kavintheran, Latiff, Anas Abdul, Harun, Sulaiman Wadi

“…However, the SOA-based SWFL exhibits a much better SMSR of between 10 to 20 dB as compared to the SMSR of the EDFA-based SWFL due to the inhomogeneous broadening properties of the SOA.…”

High power and compact switchable bismuth based multiwavelength fiber laser by Ahmad, Harith, Zulkifli, Mohd Zamani, Thambiratnam, Kavintheran, Latif, S.F., Harun, Sulaiman Wadi

“…A compact switchable multiwavelength fibre laser (SWFL) is proposed and demonstrated using a bismuth based erbium doped fibre amplifier (Bi-EDFA) and a Sagnac loop mirror (SLM) in a ring cavity. …”

Stable power multi-wavelength fibre laser based on four-wave mixing in a short length of highly non-linear fibre by Awang, Noor Azura, Zulkifli, Mohd Zamani, Latif, Amirah Abdul, Harun, Sulaiman Wadi, Ahmad, Harith

“…The multi-wavelength fibre laser is configured in a ring cavity and only needs a low power erbium doped fibre amplifier (EDFA) as the gain medium to generate 11 lines in the range of 1582-1600nm with a signal-to-noise ratio (SNR) of 43dB. …”
