Power-dependent coupling and switching in prism coupling to ZnO waveguides

Abstract

Efficient prism coupling into a thin-film waveguide requires that the component of the incident- field wave vector inside the prism match that of the guided-wave wave vector, if one of the waveguiding media is characterized by an intensity-dependent refractive index, the guided-wave wave vector (and hence the coupling process) becomes power- dependent. A decrease in coupling efficiency has been predicted1 and observed experimentally (change of ~30%).2 Other effects such as switching5 and optical bistability (assuming plane wave input)4 have also been predicted and observed in some systems.5 We report large (factor of 20) changes in coupling efficiency and switching in ZnO thin-film waveguides excited by high-power pulses from a doubled Nd:YAG laser.
