The observation of milliwatt-power optical bistability at room-temperature in interference filters based on ZnSe spacers is reported. Switching times of a few milliseconds have been achieved using 514 nm wavelength radiation at an irradiance of ~250 W cm-2. The device has been operated in a steady-state manner and switched between the two stable states by an external beam. © 1984.
