Abstract: | With unified colored noise approximation, the steady state distribution function in dispersive optical bistability including both
intensity and phase fluctuations is obtained. The parameter plane of
the first-order-like phase transition is also derived with numerical method. It is found that the number of extremes at non-zero values of the output field in the steady state distribution function is changed from zero, two to four. It is shown that the strengths of the intensity fluctuation and the phase fluctuation have great effect
on the first-order-like phase transition. |
