Temperature-Compensated Humidity Sensor Based on Hole-Assisted Three-Core Fiber
A temperature-compensated humidity sensor based on hole-assisted three-core fiber (HATCF) has been demonstrated. The three cores of HATCF act as two in-fiber directional couplers with a common communal direct-passing arm. The simultaneous measurement of temperature and humidity is achieved by integrating the refractive index matching solution and agarose film into the two in-fiber directional couplers respectively. The measured temperature and RH sensitivities are 3.399 nm/°C and 0.043 nm/%RH, respectively. Due to the capability of temperature compensation, the proposed sensor has the potential to be used for high precision humidity measurement.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
