Abstract: A high speed optical switch may include a plurality of pairs each having a length Lπ that may be connected in series. All switching may be accomplished in the high speed optical switch by discharging one arm in a pair (e.g. a single Lπ) at a time. Lπ may refer to a guide length used to induce a relative π phase shift. Each of the plurality of pairs may have two arms with both arms being initially charged. If both arms in any give pair have the same state, (e.g. either charged, uncharged, or charging) a ‘1’ may be transmitted through that pair. If the arms are in opposite states, (e.g. charged or uncharged) a π phase shift may be produced and a ‘0’ may be transmitted through that pair. For example, a first pair in the series may be recharged while other pairs are using in switching.

Abstract translation: 高速光学开关可以包括多个对，每对具有串联连接的长度Lpi。 所有的切换都可以在高速光学开关中通过一次放电一对（例如单个Lpi）来实现。 Lpi可以指用于诱导相对pi相移的引导长度。 多个对中的每一对可以具有两个臂，其中两个臂最初被充电。 如果任何给予对中的两个臂具有相同的状态，（例如，充电，不充电或充电）a'1'可以通过该对发送。 如果臂处于相反的状态（例如充电或不带电），则可能产生pi相移，并且可以通过该对传输“0”。 例如，串联中的第一对可以在其他对在切换中使用时被充电。
