Optical sensors
Researches in the field of optical sensors benefit from the works developed in integrated optics, either concerning technological developments or models. The main line of this thematic is characterized by a important activity of technology transfer (4 patent deposits since 2004) and is linked to two main projects.
Based on the electric-field induced variation of the polarization state of a laser beam probing an electro-optic crystal constituting the active part of the sensor, the system allow a simultaneous measurement of the probe temperature with a accuracy of 40 mK. Thanks to this simultaneous measurement of electric-field and temperature, the system presents a fully temperature-independent response. The creation of a laboratory spin-off is on the way.
