Optical Bistable Behavior of a Planar Quasi-Waveguide Interferometer Made with a Conjugated Organic Polymer Film

摘要

Optical bistable behavior in a quasi-waveguide interferometer with the third-order nonlinearity of the guiding film of a soluble polydiacetylene (poly-4BCMU) is demonstrated. This device shows input-output behavior analogous to that of a nonlinear Fabry-Perot etalon. The value of chi (3) for poly-4BCMU estimated from the switching power is considerably higher than the earlier reported nonresonant values measured by other methods.
