    • An optical switch for switching signal light by allowing the signal light to obliquely enter a non-linear optical thin film 1 containing nano-crystal of metal oxide from a light path disposed in an optical material, and irradiating visible excitation light to the non-linear optical thin film to induce a total reflection phenomenon, thereby controlling the reflection and transmission behavior of the signal light, wherein a difference between a temperature coefficient factor of an optical index of the non-linear optical thin film and that of an optical index of the optical material which is in contact with the non-linear optical thin film is determined to be 15×10−6/° C. or below. Preferably, it is determined to be zero or substantially zero. Thus, an influence due to the temperature increase is cancelled, and a malfunction of switching can be avoided.
    • 一种光开关,用于通过使信号光从设置在光学材料中的光路倾斜地进入含有金属氧化物的纳米晶体的非线性光学薄膜1来切换信号光,并将可见激发光照射到非线性 导致全反射现象,从而控制信号光的反射和透射行为,其中非线性光学薄膜的光学折射率的温度系数因子与光学折射率的差异 与非线性光学薄膜接触的光学材料被确定为15×10 -6 /℃或更低。 优选地,确定为零或基本为零。 因此,由于温度升高引起的影响被消除,并且可以避免切换故障。
