Sensors (Basel) 13:8827-34. 2013..1 pm in water centered at ~1,550 nm, corresponding to a Q-factor of 7.4 × 10(5), which allows for potentially significantly improved sensitivity over refractometers based on regular fiber Bragg gratings...
- Optical fiber refractometer based on cladding-mode Bragg gratingMing Han
Department of Electrical Engineering, University of Nebraska Lincoln, Lincoln, Nebraska 68588, USA
Opt Lett 35:399-401. 2010..The core mode reflection is used to compensate for the temperature cross sensitivity of the refractometer. The sensors operate in the reflection mode and can be multiplexed on a fiber in wavelength domain...
