海洋内波现象伴随着海水垂直温度的变化而发生，大多数内波探测依赖于海水垂直温度的测量。本文从理论上设计了一种基于微光纤结腔（MKR）的海水温度传感器，并进行了实验验证。研究了光纤直径和探测波长对传感灵敏度的影响。计算结果表明，在2.30-3.91 μm范围内，传感灵敏度随微纤直径的增大而增大，随探测波长的增大而增大，与实验结果吻合较好。通过选择合适的参数，测得的最大灵敏度可达22.81pm/°C。该海水温度传感器具有体积小、灵敏度高、易于制作、易于与光纤系统集成等优点，为海水温度或海洋内波现象的探测提供了一种新的光学方法，并为海水盐度、折射率、NO3-浓度等相关参数的微型传感器的组装提供了有价值的参考。
Ocean internal-wave phenomena occur with the variation in seawater vertical temperature, and most internal-wave detections are dependent on the measurement of seawater vertical temperature. A seawater temperature sensor based on a microfiber knot resonator (MKR) is designed theoretically and demonstrated experimentally in this paper. Especially, the dependences of sensing sensitivity on fiber diameter and probing wavelength are studied. Calculated results show that sensing sensitivity increases with the increasing microfiber diameter with the range of 2.30–3.91 μm and increases with the increasing probing wavelength, which reach good agreement with results obtained by experiments. By choosing the appropriate parameters, the maximum sensitivity measured can reach to be 22.81 pm/°C. The seawater temperature sensor demonstrated here shows advantages of small size, high sensitivity, easy fabrication, and easy integration with fiber systems, which may offer a new optical method to detect temperature of seawater or ocean internal-wave phenomenon and offer valuable reference for assembling micro sensors used for other parameters related to seawater, such as salinity, refractive index, concentration of NO3− and so on.
