An optical setup and relevant communication schemes interconnecting optical signals among mutually coherent optical channels are proposed to enhance the functionality of optical devices used for communication purposes. Based on self-pumped phase conjugation and two-wave mixing mechanisms in an un-doped BaTiO/sub 3/ photorefractive crystal, an optical image can be transferred from the signal-input channel to the signal-requiring channel of the emitting station. To overcome noise generated during communication, two different approaches are presented and the associated experimental results also demonstrated.
