We are utilizing photonic sensor technology for fabricating temperature, pressure and humidity sensors that can be deployed in a variety of environments including harsh environments such as oil and gas wells. By utilizing a common sensing methodology based on commercially established light sources for three different environmental variables important to manufacturing, we seek to leverage economies of scale to reduce fabrication, calibration and deployment costs. In the first phase of this research program we are quantitatively characterizing the responsivity, sensitivity and stability of FBG sensors operating at telecommunication wavelengths under a wide variety of relevant environmental conditions. This work will enable the deployment of low cost intelligent sensor networks that can be remotely interrogated to validate the sensor performance
