摘要： A data distribution system transmitting and receiving a large capacity of data such as image data smoothly without incurring a delay over an optical fiber line located between a data sever and a client device. In the data transmission system, a plurality of client devices are bus-connected through an optical fiber to a data server transmitting and receiving data as signal light. Each of the client devices has a client optical switch and is connected with a client access device. The client optical switch is structured with a thermal-lens forming element and a signal-light path shifting member. When any of the client devices forwards an access command to its own client access device, control light is irradiated from the client access device to the own client optical switch thus effecting a switchover. Thus, transmission data of from the data server is stored in a data storage of the relevant client device.

摘要： A flip-flop circuit of the present invention includes a first switch and a second switch which are connected in series to each other. The first switch includes: two input ports upon which light source light and signal light are incident; two output ports for outputting an optical output; and a thermal lens forming element for forming a thermal lens in a predetermined optical inputting condition. Although the second switch is composed in the same manner as that of the first switch, a relation between the wave-lengths to be utilized is inverted. When a state is changed from OFF to ON, a pulse signal is inputted for setting and one of the rays of output light of the second switch is fed-back to the first switch so as to maintain the state of ON. When the state is changed from ON to OFF, a pulse of additional signal light is inputted. Due to the foregoing, the two states of ON and OFF can be stably maintained.
