|Title:||Characterization of optical fiber long period grating refractometer with nanocoating|
Pinto, J. L.
|Keywords:||Optical fiber sensor|
|Abstract:||In this work is studied the response of optical fiber long period grating (LPG) to changes of the refractive index of the external media relatively to variations of wavelength and in transmission. The response of the LPG to refractive index greater and lesser than to cladding is investigated. A nanolayer was deposited onto the fiber to increase the sensitivity of the LPG to refractive index of the external media higher than cladding. The film modifies the rates of effective modes of cladding, thus improving the response of the changes in the refractive index of the external media higher than that in the refractive index of the cladding (ncl ≈ 1.457). The Langmuir–Blodgett technique was used for the deposition of the nanolayer.|
