All-optical bistability (AOB) is one of the key optical effects used for fast information processing. We report a low-power AOB device with counterclockwise hysteresis, which is based on a twisted nematic liquid crystal on a metal-insulator-metal (MIM) structure. The counterclockwise hysteresis is achieved by using the transmitted light from the MIM structure, as an output. The switching time from low to high reflectivity is measured to be 170 ms. The design of AOB devices with clockwise or counterclockwise hysteresis is also discussed.
