制作了平均腰径（d(avg)）分别为4.05和2.89 μ m的直列单模锥形光纤马赫-曾德尔干涉仪（MZI-SMTF），并对其周围介质的温度和湿度敏感性进行了测量和比较。湿度和温度分别在0% ~ 90%和28℃~ 40℃范围内测量。研究了系统在50% RH和90% RH条件下，在28℃左右的温度下的稳定性。平均腰径4.05 μ m的MZI-SMTF-1的湿度和温度灵敏度分辨率分别为0.02 nm/% RH和0.05 nm/ 0.1℃，平均腰径2.89 μ m的MZI-SMTF-2的湿度和温度灵敏度分辨率分别为0.01 nm/% RH和0.025 nm/ 0.1℃。
In-line single-mode tapered-fiber Mach-Zehnder interferometer (MZI-SMTF) with average waist diameters (d(avg)) of 4.05 and 2.89 mu m have been fabricated, and both the temperature and the humidity sensitivity of the surrounding media have been measured and compared. The humidity and the temperature were measured over the ranges from 0% to 90% and 28 degrees C to 40 degrees C, respectively. The stability of the system at 50% RH and 90% RH was investigated, while the temperature of the chamber was maintained at about 28 degrees C. The humidity and temperature sensitivity resolution values were 0.02 nm/% RH and 0.05 nm/ 0.1 degrees C for the MZI-SMTF-1 with an average waist diameter of 4.05 mu m, while they were 0.01 nm/% RH and 0.025 nm/ 0.1 degrees C for the MZI-SMTF-2 with an average waist diameter of 2.89 mu m.
