Abstract

This letter describes the development and characterization of a novel optical fiber relative humidity (RH) sensor leveraging Localized Surface Plasmon Resonance (LSPR). The sensor utilizes an in-house synthesized GO-ZnO nanocomposite (NC)-doped silica film coated on gold nanoparticle coated U-bend plastic-clad silica (PCS) fiber. It shows a linear response across a broad RH range of 15-90%, with a sensitivity of 0.1359 nm/%RH, and features rapid response and recovery times of 5s and 7s. The sensor’s response is fully reversible and repeatable.

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.
