Abstract:
The optical bistability and multistability behavior in a ring
cavity for the four-level open
atomic system, driven by two coupling fields has been analyzed. It is shown
that the presence
of exit rate from cavity is having a dominant effect on generating the
optical bi(multi)
stability on the system. We find that, the effects of the injection rates
might be of use to
control the threshold intensity. Also, it is found that optical bistability
(OB) can convert to optical multistability (OM) or vice versa via
the effect of intensity and detuning of the coupling fields.
