Photoconductive Multiplexing by ZnO : Zr:F Thin Solid Films

Abstract EN

Within this work, the nonlinear optical properties and electrical effects exhibited by zinc oxide thin films codoped with zirconium and fluorine are reported.

The development of a simple photoconductive multiplexor system is proposed.

The samples were prepared by the ultrasonic spraying technique (UST).

Spectroscopic studies and a vectorial two-wave mixing method were carried out with a nanosecond Nd:YAG laser system at 532 nm.

Experimental results indicate that after the zirconium and fluorine doping, a strong third-order optical nonlinearity can be developed in the ZnO films.

The nonlinear optical response seems to be dominantly originated by a two-photon absorption closely related to a photoconductive phenomenon.
