Analytical modeling and analysis of a coherent OFDM-WDM optical fiber transmission system with raman amplifier in presence of fiber nonlinearities

Fahmida Hossain Tithi (Department of Electrical and Electronic Engineering (EEE), BUET, 2021-06-08)

Performance of optical transmission systems are very much limited by fiber nonlinear effects such as self-phase modulation (SPM), cross-phase modulation (XPM), four-wave mixing (FWM) and crosstalk due to optical amplifiers. ...
Suppression of stimulated brillouin scattering effect using self-phase and cross-phase modulation

Fahmida Hossain Tithi (Institute of Information and Communication Technology (IICT), 2011-07)

Stimulated Brillouin scattering (SBS) is a resonant nonlinear optical interaction with the material that results in transmitted light being scattered back towards the input. Although high power lasers are available to ...
