Abstract

Two types of all-optical bistability were observed in polydiacetylene Langmuir—Blodgett (PDALB) films layered on rf-sputtered Corning 7059 slab-type waveguides with fused-quartz substrates. One bistability originating from optical nonlinear coupling between a prism and a PDALB—Corning hybrid waveguide produced input and output curves with hysteresis characteristics. The other type of bistability was observed in the hybrid waveguide with a nonlinear distributed-Bragg reflector of the PDALB top layer. We cannot yet determine whether the origins of both bistabilities are electronic or thermal.
