Abstract
Considering the relationship between the average photon and the input signal power,the output tune characteristics were analyzed and simulated based on the carrier density rate equation.The relationship between the cavity reflective index and carrier density was also taken into account.The bistable phenomena was obtained at certain input optical power and wavelength.The bistability loop width first increases and then discreases with input optical power.The bistability loop width increases versus pump optical power.The gain is magnified at certain area when the wavelength is bigger than center wavelength.
