    • In accordance with an exemplary embodiment of the present invention, an optical interleaver/deinterleaver includes a substrate having at least one window therein. The interleaver/deinterleaver further includes a first optical waveguide and a second optical fiber, which are disposed over a substrate. The first and second optical waveguides are coupled together at at least two locations to form optical couplers at each of the locations. The first optical waveguide has a first length between the two locations, and the second optical waveguide has a second length between the two locations wherein the first length is smaller than the second length. Illustratively, the first optical waveguide is disposed over the window, so that the window is along the first length of the first optical fiber. In accordance with another exemplary embodiment of the present invention, a method of interleaving/deinterleaving optical signals includes providing a first optical waveguide and a second optical waveguide, which is coupled to the first optical fiber at at least two locations. The method further includes adjusting a length of the second optical waveguide to coarsely adjust channel separation, and applying laser energy to the first optical waveguide to finely adjust the channel separation.
    • 根据本发明的示例性实施例,光交织器/解交织器包括其中具有至少一个窗口的基板。 交织器/解交织器还包括设置在衬底上的第一光波导和第二光纤。 第一和第二光波导在至少两个位置处耦合在一起以在每个位置处形成光耦合器。 第一光波导在两个位置之间具有第一长度,并且第二光波导在第一长度小于第二长度的两个位置之间具有第二长度。 示例性地,第一光波导设置在窗口上方,使得窗口沿着第一光纤的第一长度。 根据本发明的另一示例性实施例,一种交织/解交错光信号的方法包括提供在至少两个位置处耦合到第一光纤的第一光波导和第二光波导。 该方法还包括调整第二光波导的长度以粗调整通道分离,以及将激光能量施加到第一光波导以精细调节通道间隔。
