Nonlinear self-focusing and absorption effects were investigated in nanostructured SnO[sub 2]:SiO[sub 2] by means of z-scan techniques. The results show electronic nonlinearity with the real part of the cubic susceptibility ranging between 0.5 and 2.3×10[sup -20] m[sup 2]/V[sup 2]. Nonlinear dissipative effects appear to be caused by two-photon absorption involving localized states at the cluster interfaces, controlled by oxygen nonstoichiometry. As a result, synthesis can be optimized to give a wide-band-gap semiconductor-doped glass with good figure of merit for nonlinear directional couplers. © 2004 American Institute of Physics.
