A novel, to our knowledge, device based on a tapered optical fiber with a double-layer deposition including a metallic media is presented, and its properties are studied. The main novelty of the device consists of the introduction of a dielectric layer, whereas the systems depicted in the literature are simply metal-coated tapered fibers. The presence of the dielectric layer permits one to tune the response of the device to the refractive index of the surrounding medium. We have proved the suitability of this scheme for refractive-index sensing by depicting two measurement modes, namely, total power attenuation and spectral transmittance.
据我们所知，本文提出了一种基于具有双层沉积（包括金属介质）的锥形光纤的新型器件，并对其特性进行了研究。该器件的主要新颖之处在于引入了一个介电层，而文献中描述的系统仅仅是金属涂层的锥形光纤。介电层的存在使人们能够调节该器件对周围介质折射率的响应。我们通过描述两种测量模式，即总功率衰减和光谱透射率，证明了该方案用于折射率传感的适用性。
