    • An optical switching core (100) is disclosed that includes a plurality of input optical tiles (200(i)) and output optical tiles (200(o)) for directing optical beams between various input and output ports coupled to optical fibers. Each of the optical tiles includes a collimating optics array (210) for transmitting a plurality of incoming optical beams and a transparent beam directing array (220) optically coupled to said collimating optics array for redirecting said plurality of incoming optical. Two or more optical tiles are rotated about an optical axis with respect to one another to provide a compact, modular design. Drive electronics (290) may be incorporated on the tile or off of a tile. A method for fabricating a compact, modular switching core is also disclosed that enables the independent fabrication and testing of collimating optics and beam directing arrays and passive alignment of the same on a frame.
    • 公开了一种光学切换核心(100),其包括多个输入光瓦片(200(i))和输出光瓦片(200(o)),用于将光束引导到耦合到光纤的各种输入和输出端口之间。 每个光瓦片包括用于传输多个入射光束的准直光学阵列(210)和光耦合到所述准直光学器件阵列的透明光束定向阵列(220),用于重定向所述多个入射光学器件。 两个或更多个光瓦相对于彼此围绕光轴旋转以提供紧凑的模块化设计。 驱动电子器件(290)可以并入瓷砖或瓷砖上。 还公开了一种用于制造紧凑型模块化开关芯的方法,其使得能够独立地制造和测试准直光学元件和光束定向阵列,并使其在框架上的被动对准。
