摘要： A layered optical cross-connect switches signals from a first set of optical fibers to a second set of optical fibers. The optical cross-connect comprises at least two switching layers. The input ports and the output ports of each switching layer are fully interconnected. At least one switching layer is configured to switch at least two signals from the same optical fiber from the first set of optical fibers to the second set of optical fibers. For example, in a wavelength-division multiplex (WDM) system, a switching layer can switch signals from different WDM channels having different wavelengths.

摘要： A method and apparatus for curvature-resistant micro-mirror structures to reduce light beam coupling loss due to mirror curvature in free-space micro-machined optical switches is presented. As a significant contributor to light beam coupling loss is the curvature of the micro-mirrors in these cross-connect systems, an improved thick mirror slab utilizing a phosopho-silicate glass (PSG) core is constructed. The PSG core is sandwiched between two poly-silicon layers, thus providing an enhanced, bending-resistant structure which protects the PSG core from the release etchant used in surface micro-machining and substantially reduces mirror curvature. The reflective layer is laid down on top of the enhanced, bending-resistant structure.

摘要： 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.
摘要翻译：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。

摘要： An apparatus comprises an optical transmitter that comprises a processor and at least one optical modulator. The processor is configured to generate electronic representations of at least two pre-dispersion-compensated phase-conjugated optical variants carrying a same modulated payload data for transmission. The at least one optical modulator is configured to modulate the electronic representations, wherein an amount of dispersion induced on the pre-dispersion-compensated phase-conjugated optical variants depends on an accumulated dispersion (AD) of a transmission link through which the pre-dispersion-compensated phase-conjugated optical variants are to be transmitted. The amount of dispersion induced on the phase-conjugated optical variants may be approximately −AD/2, where AD is the accumulated dispersion of the transmission link. The pre-dispersion-compensated phase-conjugated optical variants are different from one another in one or more dimensions such as the polarization of light, the time of transmission, the spatial localization, the optical carrier wavelength, or the subcarrier frequency during transmission.
