RT Conference Proceedings T1 Towards Simultaneous Absorption and Refractive Index Sensing using Integrated Photonics. A1 Torres-Cubillo, Antonia A1 Sánchez-Postigo, Alejandro A1 Wanguemert-Pérez, Juan Gonzalo A1 Molina-Fernández, Íñigo A1 Halir, Robert K1 Optica integrada K1 Fotónica AB Photonic integrated sensors traditionally detect changes either in optical amplitude or phase. Here we experimentally demonstrate a sensing architecture which measures both amplitude and phase, enabling simultaneous detection of changes in absorption and refractive index.
