In photorefractive four-wave mixing, when two counter-propagating wave fronts of pump beams match, a phase conjugate beam is generated on the probe beam. Here we propose an optical switch or optical hub with security functions as an application example of this phase matching switching to optical communication devices. To confirm the basic property of the security function, two-wave mixing configuration was used as the substitution for the four-wave mixing configuration.
