摘　　要：We experimentally investigate the resonant and nonresonant second-harmonic generation in a single cadmium sulfide（Cd S） nanowire. The second-order susceptibility tensor is determined by analyzing the forward secondharmonic signals of the Cd S nanowire. Our results show that（1） d33∕d31=-2.5 at a nonresonant input wavelength of 1050 nm;（2） d33∕d31=-1.9 at a resonant wavelength of 740 nm. The difference can be attributed to the polarization-dependent resonance.We experimentally investigate the resonant and nonresonant second-harmonic generation in a single cadmium sulfide（Cd S） nanowire.
