✦ Synopsis

We propose and study a coupling system composed of the tapered ÿber and the microsphere with nonlinear medium. The optical bistability and di erential ampliÿcation caused by optical Kerr e ect is demonstrated using a geometrical method. We show that their operation characteristics can be controlled by parameters: linear phase detuning, attenuation coe cient and real amplitude coupling coe cient.
