    • A method and apparatus for minimizing optical loss associated with light beam divergence in a free-space micro-machined optical switch is presented. The coupling efficiency of a free-space micro-machined optical switch, that is, how efficiently the switch transfers an optical light beam from an emitting optical fiber to a receiving optical fiber, is obtained by calculating the overlap integral of the wave functions of an optical beam taken in a free-space mode at an entry point in the switch and in a fiber mode at a receiving fiber facet of the optical switch. Since the optical light beam diverges as it propagates through the optical switch, and the propagation distance increases with mirror size, that coupling efficiency is limited by the ratio of the optical light beam radius and the mirror radius of the switch. Thus, through careful measurements it becomes clear that an optimal value, for a given switch, of the ratio of the size of the beam in relation to the size of the mirror of the optical switch can be determined to optimize coupling efficiency and minimize data loss.
    • 提出了一种用于最小化与自由空间微加工光开关中的光束发散相关联的光损耗的方法和装置。 通过计算自由空间微加工光开关的耦合效率,即开关将光束从发射光纤传递到接收光纤的效率是有效的, 在光开关的接收光纤面处,在开关的入口点处以光纤模式以自由空间模式拍摄的光束。 由于光学光束在通过光学开关传播时发散,并且传播距离随着镜面尺寸而增加,所以耦合效率受到光束半径与开关镜面半径的比率的限制。 因此,通过仔细测量,可以清楚的是,可以确定给定开关的光束尺寸与光开关的反射镜尺寸之比的最佳值,以优化耦合效率并最小化数据丢失 。

    • A non-blocking crossconnect apparatus includes a primary bi-directional crossconnect device and a plurality of secondary bi-directional crossconnect devices. The primary crossconnect device has a plurality of pairs of bi-directional signal ports. A first one of each of the plurality of pairs of the bi-directional signal ports are arranged in a first set and a corresponding second one of each of the plurality of pairs of the bi-directional signal ports are arranged in a second set. Each secondary crossconnect device is associated with a respective one of the plurality of pairs of bi-directional signal ports and has a pair of secondary bi-directional signal ports and a pair of bi-directional signal leads. A first one of each pair of the bi-directional signal leads is operably connected to a respective one of the bi-directional signal ports in the first set and a second one of each pair of the bi-directional signal leads is operably connected to a respective one of the bi-directional signal ports in the second set. By utilizing symmetry and the bi-directional nature of communication lines, the present invention yields a rearrangeably non-blocking crossconnect apparatus as well as a strictly non-blocking crossconnect apparatus.
