    • An improved low-loss waveguide crossover uses an out-of-plane, such as vertical, waveguide to bridge over any number of waveguides with very low, or essentially no, optical loss or crosstalk. Optical signals transmitted in a waveguide system having the improved waveguide crossover can cross over one or multiple transverse waveguides with a greatly reduced loss of signal intensity by using a second waveguide (such as a bridge) positioned in a second plane different from the plane containing the transverse waveguides. An optical signal from the input waveguide is coupled efficiently through directional coupling to the bridge waveguide and optionally from the bridge waveguide to the output waveguide. Methods for fabricating the improved waveguide crossover are described.
    • 改进的低损耗波导交叉使用诸如垂直波导的平面外的桥接在任何数量的波导上,具有非常低或基本上没有的光损耗或串扰。 在具有改进的波导交叉的波导系统中传输的光信号可以跨越一个或多个横向波导,通过使用位于不同于包含第二波导的平面的第二平面中的第二波导(例如桥),信号强度的损失大大降低 横向波导。 来自输入波导的光信号通过定向耦合到桥式波导并且可选地从桥式波导到输出波导有效地耦合。 描述了制造改进的波导交叉的方法。
