摘要
研究一种新型无热化阵列波导光栅,这是由聚合物组成的一种新型阵列波导光栅。阵列波导光栅对温度的依赖性受波导物质的折射率、热膨胀系数和波导芯的尺寸影响,所以,通过调节这些参数就可以减小温度对阵列波导光栅的影响。优化得到全聚合物型阵列波导光栅在温度20℃～70℃范围内波谱漂移小于常规型AWG结构的0.5%。
A novel athermal arrayed waveguide grating （AWG）is demonstrated by this study. The arrayed wave grating is composed of polymer materials on a polymer substrate. The temperature-dependent wavelength shift of the AWG depends on the refractive indices of the materials and the size of the waveguide and the coefficient of thermal expansion of the polymer substrate. The athermalization of the AWG can be realized by the control of the material and structural parameters of the waveguide. When the temperature changes range from 20 to 70 ℃, spectrum shift of athermal AWG was less than 0.5 % of the normal silica/silicon AWG structure.
