Multi-device wavelength selection switch

Described herein is a wavelength selective switch (100) comprising an input fiber array (102). The array (102) includes two or more columns of optical fibers spatially offset in one or both of a switching dimension or a dispersion dimension of the wavelength selective switch (100). Each column of optical fibers (102A, 102B) is adapted to project a respective light beam. A switching engine (112) is positioned to receive the light beam and apply angular switching to the light beam to direct the light beam to a respective output fiber. The light beams are encoded at respective angles or polarization states such that each column of light beams is incident on a different region of a switching engine (112). 本文描述了一种波长选择开关(100)，其包括输入光纤阵列(102)。阵列(102)包括在波长选择开关(100)的切换维度或色散维度中的一者或两者上空间地偏移的两列或更多列光纤。每一列光纤(102A、102B)适于投射相应光束。切换引擎(112)被定位成接收所述光束并且对所述光束施加角度切换，以将所述光束引导至相应的输出光纤。所述光束以相应的角度或偏振状态进行编码，使得每一列光束入射到切换引擎(112)的不同区域上。
