Claudio J. Oton (born in Cartagena, Spain, 1978) received his degree in Physics in 2000 and PhD in 2005 in University of La Laguna (Spain). Then he spent 4 years in the Optoelectronics Research Centre, University of Southampton, UK as a post-doctoral researcher and Marie Curie fellow. In 2009 he joined the Nanophotonics Research Centre, in Universidad Politecnica de Valencia, (Spain) as a Senior Research Fellow. Finally, in 2012 he joined Scuola Superiore Sant'Anna in Pisa (Italy) as an Assistant Professor, and from 2022, Associate Professor. He works in the Institute of Mechanical Intelligence in the research group Photonic Sensing Integrated Systems. His main fields of expertise are photonic sensors and silicon photonics. He is author of more than 150 scientific papers and conferences, which have generated more than 3000 citations, and has participated in several international research projects and contracts. In particular, he has been coordinator of projects funded by the Italian Space Agency, the Italian Ministry of Economic Development, the EU FP7 program, and  has also coordinated several research contracts with industrial partners. He is also Associate Editor of the Q1 journal Optics and Laser Technology (Elsevier, IF 5.0) and member of the Optica Society.

His main research fields are:

  • Silicon photonics: Optical design and characterization of optical devices integrated in silicon technology. His main contributions regard design of optical switches, grating couplers, interleavers, crossings, nonlinear devices, and integrated optical systems for telecommunications and sensing.
  • Optical fiber sensors: Distributed and FBG fiber sensing systems. Topics include Distributed Acoustic Sensors (DAS), Brillouin OTDA systems, Raman-based Distributed Temperature Sensors, and Fiber Bragg grating (FBG) sensing systems.
  • Photonic integration of optical sensors: Design and testing of photonic integrated circuits to be used as interrogators of optical sensing systems, such as FBGs or biophotonic sensors.



Claudio Oton is coordinating the postgraduate course "Lab of Optical Sensing and Components" and "Photonic Simulations with Python" and he is teaching assistant in the course "Optical Fiber Sensor Systems".
