We firstly report on the fabrication of Cu2+ -doped germano-silicate glass fiber for nonlinear optical devices application by using modified chemical vapor deposition and solution doping processes. Broadband absorption near 700nm due to the 3d-shell electron transitions of Cu2+ ions from the ground state to the excited states was observed. The resonant nonlinearity of the Cu2+-doped fiber was estimated to be 5.5×10-17m2/W by measuring the phase shift of the fringes obtained from the long-period fiber grating pair upon pumping with a laser diode at 980nm and non-resonant nonlinearities were also measured to be 4.114×10-21m2/W by the continuous wave self-phase modulation method.
