Optical Fiber Humidity Sensor Based on Lossy Mode Resonances
A novel optical fiber humidity sensor based on lossy mode resonances (LMR) has been developed. LMRs are supported here by a thin Indium Tin Oxide (ITO) coating fabricated onto an optical fiber core via a sol-gel dip coating. ITO coated optical fiber devices present a resonant maximum absorption peak in the infra-red region which is shifted to higher wavelengths when the refractive index of the ...
متن کاملFabrication and Characterization of the Fiber Optical Taper for a Surface Plasmon Resonance Sensor
For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...
متن کاملGraphene Oxide in Lossy Mode Resonance-Based Optical Fiber Sensors for Ethanol Detection
The influence of graphene oxide (GO) over the features of an optical fiber ethanol sensor based on lossy mode resonances (LMR) has been studied in this work. Four different sensors were built with this aim, each comprising a multimode optical fiber core fragment coated with a SnO₂ thin film. Layer by layer (LbL) coatings made of 1, 2 and 4 bilayers of polyethyleneimine (PEI) and graphene oxide ...
متن کاملOptical fiber biosensor based on Lossy Mode Resonances
The detection of the specific binding between antigen and antibody is perhaps the most used technique for diagnosis in medicine and biology. More specifically, the utilization of optical devices, which enable the detection of specific antigen-antibody binding by means of the monitorisation of their spectral response, is extensively exploited in immunoassays. In this field, Surface Plasmon Reson...
