Fibre Tip Sensor with Embedded FBG-LPG for Temperature and Refractive Index Determination by means of the Simple Measurement of the FBG Characteristics

<div>Temperature correction effect: Bragg reflected power before (red circles) and after (black square) the thermal compensation. The fitting curve describes the RI response of the sensor at 21°C (the same of Figure <a href="../fig6/">6</a>).</div>
