| 摘 要： | 为了让温度传感器在集成化全光控制中找到实现途径,提出一种基于非局域空间光孤子传输的温度传感器的理论方案.以铅玻璃作为非局域空间光孤子的传输介质,通过研究圆柱形铅玻璃中, 中心入射光束在传输过程中的相移问题, 得出在环境温度0.32 ℃的改变就可以引起孤子π相移的结论.此温度改变对相移的调制有望为基于干涉仪原理的温度传感器提供一个可行且灵敏度较高的实现方案.

| Abstract: | In order to accomplish the all-optical control in the aspect of tempaerature sensors, a theoretical design of temperature sensors is proposed based on the nonlocal spatial solitons. Taking lead glass as the propagation media of the soliton, the phase shift of the center-incident soliton is studied in the cylindrical lead glass. It is concluded that a temperature change of 0.32 ℃ can lead to π phase shift of the nonlocal solitons. The phase shift modulation by the temperature change will be a practicable and sensitive design of the temperature sensor based on the interferometer theory. |
