A light self-routing device, namely, a light connecting device capable of indicating an address of information only by light signals. The light connecting device according to the invention comprises a photoelectric input/output elements (1) with functions of light threshold process and light memory, a polarized beam splitter (2), and light delay circuits (3). The light input signal includes a timing signal (11) and an information signal (13), and those are inputted to the device in the described order. The timing light signal having different delay timing from the other signals is separated from the other signals to be sequentially inputted into the respective photoelectric input/output elements through light delay circuits having different delay timings. If the address light signal is incident in synchronization with that of the timing light signal, only the element on which the address and timing lights are simultaneously incident is operated turn ON and acts as a light amplifier by injecting current to amplify the information signals for outputting. Thus, the light connecting device of the invention could realize self-routing operation only by light signals in which the address of information is specified by the address light signal. |
