Patent abstract
An optical logic device has a first mirror confronting a second mirror, and a saturable absorber located between the mirrors. Radiation that is output from the device is output via the first mirror. The reflectivity of the first mirror is such that, in use, for incident radiation which has an intensity that is above a given value, the intensity of exiting radiation is below a threshold. For incident radiation that is below the given value, the intensity of exiting radiation is above the threshold.
