摘要： An arrayed-waveguide grating (AWG) whose thermal-shift characteristics can be tailored to match the corresponding characteristics of another optical device (e.g., a solid-state laser or modulator) to which the AWG is intended to be coupled. In one embodiment, the physical means that enable the match of the thermal-shift characteristics include one or more wedge-shaped structures placed into one or both of the waveguide-coupling regions of the AWG. By appropriately selecting the structure's material, shape, and orientation and also the number of structures, the AWG can be manufactured to have substantially the same thermal-shift coefficient as the other optical device. As a result, the AWG can advantageously remain in optimal spectral alignment with the optical device despite temperature fluctuations and, as such, does not require a thermostat or temperature controller for proper operation.
摘要翻译：阵列波导光栅（AWG），其热移动特性可以被调整以匹配AWG旨在耦合到的另一光学装置（例如，固态激光器或调制器）的对应特性。在一个实施例中，能够匹配热偏移特性的物理装置包括放置在AWG的一个或两个波导耦合区域中的一个或多个楔形结构。通过适当地选择结构的材料，形状和取向以及结构数量，AWG可被制造成具有与其他光学装置基本上相同的热移动系数。因此，尽管温度波动，AWG可以有利地保持与光学装置的最佳光谱对准，并且因此不需要用于正常操作的恒温器或温度控制器。
