基于光纤柔性板的共封装光学机箱温度传感研究
Research on temperature sensing for co-packaged optics chassis based on fiber optic flexible board
摘要
Abstract
To address the thermal management requirements arising from the high heat flux density of co-packaged optics(CPO)chassis,this paper proposes a temperature sensing scheme for the CPO chassis based on fiber optic flexible circuits(FOFC).The scheme utilizes any two channels within the FOFC to construct an unbalanced Mach-Zehnder interferometer,achieving temperature measurement by monitoring the wavelength shift of the interference spectrum.Experimental results dem-onstrate that within the temperature range of 30～70 ℃,the proposed scheme achieves a temperature sensitivity of 13.7～16.2 pm/℃ and a measurement accuracy of±1.5 ℃.Moreover,the sensitivity does not vary significantly with different chan-nel combinations,indicating good application potential.关键词
