Abstract:
We previously analyzed the effects of trapezoidal tapered gratings on the dispersive bistable characteristics of a quarter wavelength phase-shifted distributed feedback semiconductor laser amplifier (QWS-DFB-SLA). In this paper, we analyze the effects of coupling coefficient on the static bistable characteristics of a QWS-DFB SLA with a tapered or a non-tapered grating. Simulation results show that any change in the coupling coefficient can change the characteristics such as the spectral range of low-threshold bistable switching and the on-off switching contrast.
