“…The top mirror reflectivity R t determines the amount of light entering the saturable absorber and therefore controls the nonlinear reflectivity [13]. For such a device the spectral dependent power reflectivity can be calculated by using the standard formula for a FP-cavity incorporating the losses [8].…”

We have proposed a theoretical model to study bistable switching between two optical signals using a vertical cavity semiconductor saturable absorber (VCSSA) operating in reflection mode. The model is based on the carrier rate equation, which predicts cross-absorption phenomena within the absorber region. Simulations are carried out to investigate the effect of various cavity parameters on switching performance of the device. As an application, we have studied wavelength conversion of a 10Gb/s non-return-to-zero data signal, using the same model for bistable switching. 

“…Optical bistable devices are very interesting for many applications such as all-optical logic operations, optical regeneration, optical filtering, analog to digital optical conversion, and polarization modulation and switching [1][2][3][4][5][6]. Vertical cavity semiconductor optical amplifiers (VCSOAs) are attractive for many applications since they have small size, high coupling efficiency to the fiber, low cost, 2D fabrication, and polarization independent gain [7][8][9][10].…”

We analyze the bistable characteristics of quantum dot vertical cavity semiconductor optical amplifier integrated with saturable absorber. The device demonstrates bistable characteristics in the input-output powers which can be controlled by changing the voltage of the saturable absorber. We observe that the lower trigger level is more sensitive to variation of the absorption coefficient of the saturable absorber than that of upper trigger level. For clockwise and butterfly loops, we find that the upper and lower trigger levels increase as the absorption coefficient increases, and consequently the hysteresis width decreases. For counter clockwise, the upper and lower trigger levels decrease as the absorption coefficient increases and the corresponding hysteresis width increases.
