摘要： An optical switch is proposed, for routing an optical transmission signal according to an optical control signal, including one or more optical control ports; three or more optical transmission ports; a light director; and a thermally driven light mill; where the light mill and the light director are arranged with respect to each other, to the one or more control ports and to the three or more transmission ports such that: illumination of a respective one of the one or more control ports by a control beam carrying the control signal drives the light mill to rotate towards a respective position in which the light director is arranged so as to direct a transmission beam carrying the transmission signal, entering the switch via a respective one of the transmission ports, to exit the switch via a respective other of the transmission ports.

摘要： In optical transmission schemes of the related art, there is a problem of delay dependency on an overhead or a flow size. In a DC network and a supercomputer network, an OCS scheme and an OPS scheme remain in an examination stage. A network of the electrical packet switching is still a main stream. In a scheme of sharing links using a dedicated wavelength, a considerable number of wavelengths is also necessary to provide full connectivity. The number of wavelengths cannot be realized and an unrealistic number considering the usable number of wavelengths such as current used C bands. In an optical network and an optical transmission system of the present invention, burst mode data transmission in which a label-based switching on an exclusively reserved dedicated wavelength is used is performed. Each node has a uniquely allocated wavelength, and thus traffics coexisting in all the network nodes do not collide. By using an optical label processor, an overhead time for establishing links between nodes is unnecessary. Reuse of the same wavelength results in further decrease in the number of wavelengths.

摘要： A thyristor switch is constituted of a pair of arms connected in anti-parallel, each of the anus including a plurality of thyristors connected in series. A controller includes a phase detecting unit configured to detect a phase of a power supply voltage supplied from an alternating-current power supply, and a gate signal generating unit configured to interrupt a gate signal when an open command is provided to the static switch and the phase of the power supply voltage detected by the phase detecting unit matches a target phase. The target phase is set outside of a phase range where interruption of the gate signal is prohibited, the phase range being set so as to include a zero crossing point at which a load current is switched in polarity.
