    • An optical cross connect switch. In this switch any optical fiber in an input set of optical fibers, each carrying a communication beam, can be cross connected to any optical fiber in an output set of optical fibers. An alignment beam is added to and aligned co-axially with the communication beam carried by each fiber in the input set of optical fibers to define a communication-alignment beam for each fiber. Each communication-alignment beam is directed within a confined optical pathway to a specific exit aperture in an input array structure. The exit apertures for all of the communication-alignment beams are arranged in a pattern defining an input array so that each communication-alignment beam can be identified by the location of its exit aperture in the input array structure. Each communication-alignment beam is formed into a cross-connection beam by a micro-lens in a first lens micro-lens array. Each cross-connection beam is directed to a lens in a second lens array by two mirrors, a first mirror in a first mirror array and a second mirror in a second mirror array. The lens in the second micro-lens array focuses the communication beams into a specific input aperture of a confined optical pathway, preferably an optical fiber, in an output array structure. Each of the confined optical pathways in the output array structure is optically connected to an optical fiber of an output set of optical fibers. A first detector array located near the second lens array monitors the position of each alignment beam and provides position information to a processor for control of the mirrors in at least one of the mirror arrays.
    • 光交叉开关。 在该开关中,输入光纤组中的任何光纤,每个携带通信光束的光纤可以交叉连接到输出光纤组中的任何光纤。 对准光束被添加到光纤的输入组中并与由每个光纤携带的通信光束同轴地对准,以限定每个光纤的通信对准光束。 每个通信对准光束被引导到一个有限的光学路径中,到达输入阵列结构中的一个特定的出射孔。 用于所有通信对准光束的出射孔以限定输入阵列的图案布置,使得每个通信对准光束可以通过其输入阵列结构中其出射孔的位置来识别。 每个通信对准光束通过第一透镜微透镜阵列中的微透镜形成为交叉连接光束。 每个交叉连接梁通过两个反射镜指向第二透镜阵列中的透镜,第一反射镜阵列中的第一反射镜和第二反射镜阵列中的第二反射镜。 第二微透镜阵列中的透镜将通信光束聚焦成输出阵列结构中的限制光学路径(优选光纤)的特定输入孔径。 输出阵列结构中的每个限制光路径光学地连接到输出光纤组的光纤。 位于第二透镜阵列附近的第一检测器阵列监视每个对准光束的位置,并向处理器提供位置信息,以控制至少一个反射镜阵列中的反射镜。

    • A CMOS image sensor with a many million pixel count. Applicants have developed techniques for combining its continuous layer photodiode CMOS sensor technology with CMOS integrated circuit lithography stitching techniques to provide digital cameras with an almost unlimited number of pixels. A preferred CMOS stitching technique exploits the precise alignment accuracy of CMOS stepper processes by using specialized mask sets to repeatedly produce a single pixel array pattern many times on a single silicon wafer with no pixel array discontinuities. The single array patterns are stitched together lithographically to form a pixel array of many million pixels. A continuous multilayer photodiode layer is deposited over the top of the many million pixel array to provide a many million pixel sensor with a fill factor of 100 percent or substantially 100 percent.
    • 具有数百万像素数的CMOS图像传感器。 申请人已经开发出将连续层光电二极管CMOS传感器技术与CMOS集成电路光刻拼接技术相结合的技术,为数码相机提供几乎无限数量的像素。 优选的CMOS拼接技术利用CMOS步进工艺的精确对准精度通过使用专门的掩模组在单个硅晶片上重复产生单个像素阵列图案多次而不存在像素阵列不连续性。 将单阵列图案光刻地缝合在一起以形成数百万像素的像素阵列。 连续的多层光电二极管层沉积在数百万像素阵列的顶部,以提供百万像素传感器,其填充因子为100%或基本为100%。
