    • The wavelength multiplexing and demultiplexing characteristics of the AWG (Arrayed Waveguide Grating) module are closely related to specificity of spectral position dependent on specific wavelengths. The positional specificity is such that when a position of the originally designed input waveguide (1) is moved horizontally in x-direction (9) along the tangential interface of the input slab waveguide (3) to the incident light propagation path, the wavelengths of light entering into the output waveguide (2) undergoes proportionate shifting. The wavelength at the output waveguide (2) shits by dλwhen the position is moved by dx in the horizontal direction from the center of the focal point of the input slab waveguide (3). The temperature dependency of the wavelength can be compensated by utilizing this positional shifting of wavelengths; namely by changing input waveguide's position on the input slab guide (3). In order to move the position of the input waveguide (1) passively upon the temperature change, it is necessary to move horizontally (x-direction (9)) the position of the originally designed input waveguide (1) attached with a temperature compensation rod (10) having larger TEC than substrate; the horizontal movement is effected when the temperature compensation rod (10) undergoes thermal expansion and contraction. The present invention features the novelty of temperature-independent AWG module and the manufacturing method, regarding specifically to improvement of optical loss and optical return, and to the suitable materials for the temperature compensation rod, which matches to the specific wavelength division spacing.
    • AWG(阵列波导光栅)模块的波长复用和解复用特性与依赖于特定波长的光谱位置的特异性密切相关。 位置特异性使得当原始设计的输入波导(1)的位置沿着输入平板波导(3)的切向界面沿x方向(9)水平移动到入射光传播路径时,波长 进入输出波导(2)的光经历比例偏移。 当位置从输入平板波导(3)的焦点的中心沿水平方向移动dx时,输出波导(2)处的波长为d 1。 通过利用这种波长的位置偏移可以补偿波长的温度依赖性; 即通过改变输入板导板(3)上的输入波导的位置。 为了将输入波导(1)的位置无源地移动到温度变化上,需要水平(x方向(9))移动附加有温度补偿棒的原始设计的输入波导(1)的位置 (10)具有比底物大的TEC; 当温度补偿杆(10)经受热膨胀和收缩时,水平运动。 本发明的特征在于独立于温度的AWG模块的新颖性和专门用于改善光损耗和光学返回的制造方法,以及与特定波长间隔匹配的用于温度补偿棒的合适材料。
