The concept of having the effective refractive index of an optical waveguide mode be independent of temperature is introduced. It is shown that this concept should be realizable with a Corning 7059 glass thin-film waveguide supported on a SiO(2)-Si substrate for a waveguide thickness of 0.37 microm. Measurements of effective refractive index as a function of temperature confirm this prediction of temperature independence in that they show a very small variation with temperature for a 0.35-microm thick waveguide in comparison with that for a 0.98-microm thick waveguide.
引入了使光波导模式的有效折射率与温度无关的概念。结果表明，对于支撑在SiO(2)-Si衬底上、厚度为0.37微米的康宁7059玻璃薄膜波导，这一概念应该是可以实现的。作为温度函数的有效折射率测量结果证实了这种与温度无关的预测，因为与厚度为0.98微米的波导相比，对于厚度为0.35微米的波导，测量结果显示其随温度的变化非常小。
