Enhanced gain saturation model of non-linear semiconductor optical amplifiers by Kharraz, Osayd M., M. Supa'at, Abu Sahmah, Atieh, Ahmed, Abdul Kadir @ Jaafar, Muhammad Zamzuri, Mahdi, Mohd Adzir

“…The rate equations are utilised with the extra gain compression term for Indium-Gallium-Arsenide material-based SOA to account for the steep relaxation oscillations behaviour of non-linear SOAs. The proposed gain saturation model is verified with experimental results that showed very good agreements with a mean square error of 0.094.…”

Investigation of Q-Switching Characteristics in Single- and Double-Spacing Multi-Wavelength Brillouin Erbium Fiber Laser by Tan, S.J., Jusoh, Z., Ali, N.M., Arof, Hamzah, Ahmad, Harith, Harun, Sulaiman Wadi

“…A multi-wavelength Brillouin erbium fiber laser (BEFL) with a Q-switching characteristic is demonstrated using a piece of non-zero dispersion shifted fiber (NZ-DSF) as a Brillouin gain medium (BGM) in conjunction with relaxation oscillation technique. The performance of the multi-wavelength short pulse generation is investigated for two different BEFL configurations for single and double Brillouin spacing outputs. …”
