TITLE: Pressure Sensing Based on Ratiometric Bragg Grating Loss in a Planar Silica Diaphragm Platform
JOURNAL: Advanced Photonics Congress JTu2A.62 
PAPER DOI IF KNOWN

Data was collected from an ANDO AQ6317B optical spectrum analyser using a Amonics ASLD-CWDM-5B-FA source. Pressure readings were recorded manually using a vacuum gauge.
This dataset contains:wavelength data (nm) and intensity data (dBm)

Data supporting etc etc 

The figures are as follows:

Fig. 2  Left axis shows the amplitude ratio of grating #2, the reference, and #3, the measurand, normalized to the zero differential
pressure point. Right axis shows the wavelength shift of the #3 Bragg grating peak with an increase in pressure.


Date of data collection: 18 January 2018
