Abstract

Theoretical and experimental investigations of the nonlinear refractive index in an erbium- doped fiber are reported. We also show that an optical switch based on twin-core erbium- doped fiber can be constructed and operated at low input optical power, in the order of 1 or 2 mW. The transient response of this fiber also is examined. The switching speed can be improved by using a signal power at a wavelength close to the resonant wavelength between the excited state and the ground state.
