ABSTRACT:
In one version, the present invention provides an optical switching device including a splitting device having a first terminal for receiving an input signal and second and third terminals, and an optical loop associated with the second and third terminals and having first and second non-linear elements and first and second directing devices. One of the first and second non-linear elements may receive an activating signal from a third directing device and, in response to the activating signal, cause the optical loop to producing first and second output signals at the first and second directing devices, respectively. In another version, the present invention provides an optical gating device. The present invention also provides an optical switching device that may include two optical gating devices and an optical toggle device.
