    Abstract: A first configuration of an optical node may include a set of degrees, each including an inbound wavelength selective switch (WSS) and an outbound WSS. The first configuration may include a first degree expansion including a first inbound expansion WSS and a first outbound expansion WSS. An expansion input of the first inbound expansion WSS may connect to an expansion output of a second outbound expansion WSS included in a second degree expansion of a second configuration of the optical node. An expansion output of the first outbound expansion WSS may connect to an expansion input of a second inbound expansion WSS included in the second degree expansion of the second configuration. A signal input to an inbound WSS of a given one of the set of degrees may be routed, via the first degree expansion and the second degree expansion, to any drop port included in the second configuration.

    Abstract: A method may include receiving, by a switching engine, an optical signal. The optical signal may carry a super-channel that includes a plurality of sub-carriers to be directed toward respective output ports. The switching engine may have a plurality of regions of pixels on which respective sub-carriers, of the plurality of sub-carriers, are incident. The method may include applying, by the switching engine, respective single beam steering gratings to first, overlapping, areas of the plurality of regions of pixels. The method may include applying, by the switching engine, one or more respective pluralities of beam steering gratings to second, overlapping areas of the plurality of regions of pixels. The method may include directing, based on the single beam steering gratings and the one or more pluralities of beam steering gratings, parts of the optical signal toward the respective output ports.

    Abstract translation: 一种方法可以包括由切换引擎接收光信号。 光信号可以携带包括要指向相应输出端口的多个子载波的超级信道。 交换引擎可以具有多个像素区域，多个子载波中的各个子载波在其上入射。 该方法可以包括由开关引擎将各个单波束转向光栅应用于多个像素区域中的第一重叠区域。 该方法可以包括通过切换引擎将一个或多个相应的多个光束转向光栅应用于多个像素区域中的第二重叠区域。 该方法可以包括基于单光束转向光栅和一个或多个光束转向光栅将光信号的一部分引导到相应的输出端口。
