    • An optical signal router for communication systems is described. The optical signal router includes a switch driver that generates a modulation drive signal containing a linear combination of a DC offset voltage and at least three electrical signals. In one embodiment, each of the at least three electrical signals has a frequency that is a unique integral multiple of a bit-rate. The optical signal router also includes an optical switch having an electrical modulation input that is electrically coupled to the output of the switch driver. The optical switch also includes an optical input that receives a time-division multiplexed optical signal including a plurality of optical subchannels. In one embodiment, each of the plurality of optical subchannels includes the bit-rate. The optical switch routes a subset of the plurality of optical subchannels to an optical output in response to the modulation drive signal.
    • 描述了用于通信系统的光信号路由器。 光信号路由器包括产生包含DC偏移电压和至少三个电信号的线性组合的调制驱动信号的开关驱动器。 在一个实施例中,至少三个电信号中的每一个具有作为比特率的唯一整数倍的频率。 光信号路由器还包括具有电耦合到开关驱动器的输出的电调制输入的光开关。 光开关还包括光输入,其接收包括多个光子通道的时分复用光信号。 在一个实施例中,多个光学子信道中的每一个包括比特率。 响应于调制驱动信号,光开关将多个光子信道的子集路由到光输出。
