This paper presents the carried out investigation on nonlinear effects in semiconductor optical amplifier (SOA); in particular two-photon absorption process and its induced free carriers. The simulation results show nonlinear phase shift and the spectral broadening is induced by nonlinear free-carrier effect after propagation through the SOA. The levels of injected carrier density in SOA are varied...
In this paper we demonstrate a single-wavelength Brillouin Fiber laser utilizing ring cavity which operated in the L-band wavelength region. The Brillouin gain medium is provided by 4 km long of Single Mode Fiber. Based on the experimental result, it shows that the maximum output Brillouin power of 9.73 dBm with an average value of 8.5 dBm was obtained as the Brillouin pump power of 16.0 dBm and pump...
