概要

By employing attenuated total reflection geometries, we have numerically analyzed optical switching due to local Kerr nonlinearity by the coupled mode theory for a lossy polydiacetylene waveguide and explored the possibility of realizing the observation of optical attenuated total reflection(ATR)switching. We have adopted a Gaussian incident beam and have taken into account beam spread. It has been found that the choice of a proper beam spread of the incident Gaussian light leads to a considerable decrease of the critical light power and the critical light intensity required for the optical switching. Moreover, the effect of the incident beam width and guided layer thickness on the critical incident intensity and the critical incident power has been discussed.
