Optical bistability and switching performance in QWS distributed coupling coefficient DFB SLA’s
Mohammad Saeed Tahvili, Mohammad Hossein Sheikhi
Optical bistability (OB) behavior in quarter-wave-shift (QWS) distributed coupling coefficient (DCC) distributed feedback (DFB) semiconductor laser amplifiers (SLApsilas) is investigated. The simulations are based on a modified transfer-matrix method, which considers grating non-uniformities along the structure as well as gain saturation effect. Switching characteristics, including structural dependence of OB in QWS DCC DFB SLApsilas is demonstrated in the steady state regime. Time-dependent analysis of OB is performed as well, and the dynamics of optical switching is demonstrated.
