Effect of wavelength detuning on hysteresis width of single mode Fabry-Perot laser diode and its impact on the realization of optical SR latch

Abstract

In this paper, we have experimentally analyzed the effect of hysteresis width on optical bistability present in single mode Fabry-Perot laser diode (SMFP-LD). Hysteresis width on optical bistability plays an important role on the latching operation. Input injected power and wavelength detuning are two parameters that can effect on the hysteresis width and hence the optical bistability. With this analysis we demonstrated simultaneous inverted and non-inverted output of optical SR latch with input set and reset data rate of 8.5 Gbps.
