Paper Abstract

We theoretically analyze the behavior of a hybrid optical bistable device that uses a tunable directional coupler filter as a modulator. The device is shown to have a great potential for applications in optical computing and optical communications. The output intensity dependencies on different input parameters are plotted and their basic features are exploited in imaging applications such as optical logical gates and other optical circuits. The spectral dependence of the pulse response of the bistable device is emphasized, suggesting the design of a very sensitive wavelength sensor.
