Sodium tellurite glasses are considered as potential candidates for non-linear optical applications because of high refractive index values and wide infrared transmittance.

亚碲酸盐玻璃一般具有较高的密度、较高的折射率、较宽的红外透过性能，同时具有较好的介电性能，一直作为非线性光学材料进行研究。

Results show that the electric field induced refractive index change in DQWs varies with the width of the intermediate potential barrier. And it decreases as the incident optical intensity increases.

结果表明，折射率改变不但与入射光强有关，更与阱中的势垒宽度有关。
