    • Arrayed waveguide grating can have one or both slab waveguides with relatively sharply folded optical paths and a mirror that provides the folding of the path. The folded optical paths through the slab waveguides can result in a more compact geometry of the waveguides through the device as well as smaller slab waveguides such that the device can be formed with a significantly smaller overall footprint. Also, arrayed waveguide gratings that cooperate with pivotable mirrors can adjust light passage through the waveguide in response to temperature changes to provide for thermally compensated operation of the device. Thus, very compact planar lightwave circuits filters are described that provide thermally compensated operation.
    • 阵列波导光栅可以具有一个或两个具有相对急剧折叠的光路的平板波导和提供路径折叠的反射镜。 通过平板波导的折叠的光路可以导致通过器件的波导的更紧凑的几何形状以及更小的平板波导,使得该器件可以形成为具有显着更小的总占地面积。 此外,与可枢转镜配合的阵列波导光栅可以响应于温度变化来调节通过波导的光通过,以提供器件的热补偿操作。 因此,描述提供热补偿操作的非常紧凑的平面光波电路滤波器。
