Study of developed scheme for optical bandwidth broadening of SOA broadband based on using a spectrally selective reflective filter

Abstract

In this work, a developed scheme for optical bandwidth broadening of Semiconductor Optical Amplifier (SOA) broadband is suggested. The proposed scheme based on using a spectrally selective reflective filter is studied by simulation. The performance of the suggested scheme and its effectiveness in optical bandwidth broadening and improvement of its steady state are investigated. An optical bandwidth of 141.42 nm is attained allowing the amplification of 8 C-WDM channels (Coarse Wavelength Division Multiplexing) with gain equals to 14.7 dB and Noise Figure variation between 8.42-11.53 dB. The impact of losses, caused by optical elements used in the suggested scheme, and the input optical power of signals needed to be amplified on the performance of the suggested scheme are studied.
