    • Methods, circuits and systems are provides to produce a bipolar signal across a load from two or more unipolar signals. In a circuit that includes a first and a second energy source, as well as a first and a second photonic switch, a first unipolar signal is generated from a first current flow across the load upon activation of the first switch. A second unipolar signal is generated from a second current flow across the load upon activation of the second switch. The bipolar signal with any desired spectral and amplitude characteristics is produced across the load by controlling the relative delay between the activation of the first and second photonic switches. Spectral content and shape of the bipolar signal can be adjusted by controlling the current flows from the one or more energy sources through, for example, modulation of the optical beams incident on the photonic switches.
    • 方法,电路和系统用于在两个或多个单极信号的负载上产生双极信号。 在包括第一和第二能量源以及第一和第二光子开关的电路中,在第一开关激活时,跨越负载的第一电流产生第一单极信号。 当激活第二开关时,通过负载的第二电流产生第二单极信号。 通过控制第一和第二光子开关的激活之间的相对延迟,跨负载产生具有任何所需频谱和振幅特性的双极信号。 可以通过例如通过入射在光子开关上的光束的调制来控制来自一个或多个能量源的电流来调节双极性信号的光谱含量和形状。
