Optical switching has been achieved between two steady states of optical bistability generated in a system with three-level atoms inside an optical cavity. The optical power switching is controlled by adding short positive (switching up) or negative (switching down) pulses to the input intensity. The coupling laser beam in the three-level atomic system is used to control the threshold value and the width of the hysteresis cycle, which can adjust and optimize the optical switching process. © 2003 American Institute of Physics.
