摘要

光功率密度和温度监测在工业生产和日常生活中具有重要意义, 依据PbSe量子点具有较高热光系数的特性, 设计了一种PbSe量子点作传感材料的全光纤马赫-曾德尔型传感器, 并在不同光功率密度和不同温度条件下对该传感器进行测试。实验结果表明:对波长为473 nm的光源光功率密度灵敏度达到1.455 nm·(mW-1·mm2), 温度灵敏度达到0.67 nm·℃-1。不仅实现了高灵敏度温度传感器, 而且也为PbSe量子点制作热光型光器件打下了基础。

Abstract

Optical power density monitoring and temperature monitoring play an important role in the industrial production and day-to-day life. In this study, an all fiber-optic Mach-Zehnder sensor with PbSe quantum dots as the sensing material is fabricated on the basis of thermo-optical characteristic of PbSe quantum dots, and the sensor is tested under different optical power densities and temperatures. The results show that the power density sensitivity of the sensor to a light with a wavelength of 473 nm is 1.455 nm·(mW-1·mm2) and the temperature sensitivity is 0.67 nm·℃-1. This study not only realizes a high-sensitivity temperature sensor, but also lays the foundation for the thermal-optical devices made by PbSe quantum dots.
