Béatrice Dagens received the master degree in Physics and Chemistry from ESPCI, Paris, France in 1992, the PhD degree in Optoelectronics from the University Paul Sabatier, Toulouse, France in 1995 and the HDR (habilitation) from University Paris-Sud, Orsay France in 2005.

She joined the optical component research department in Alcatel, Marcoussis, France in 1996. She was first responsible for the design, the realization and the measurement of SOA based interferometers for all-optical and high bit rate wavelength conversion and regeneration. Then her activity was focused on advanced laser diodes emitting at 1.3 and 1.55 µm using new materials like quantum dots, dilute nitride based active layers, and metallic ferromagnetic layers, and on Photonics Integrated Circuits.

Since end 2007, she has occupied a position of CNRS Senior Researcher at Institut d’Electronique Fondamentale, now Centre for Nanoscience and Nanotechnology (C2N), Orsay, France. Her current research includes magneto-optical, magneto-photonic and plasmonic nanostructured components for compact integrated photonic circuits and devices. From 2011 to 2016, she was deputy head of Photonic Department at IEF. From 2012 to 2014 she was CNRS officer for photonics domain. From 2012 to 2015, she has hold the chair of University Paris-Sud “Optoelectronics and Photonics”, funded by PSA. During this period she organized or co-organized three national and one international workshops on photonics (~60 to 100 attendies). Presently she is supervisor of the sino-french network (CNRS GDRI) for Photonics and Optoelectronics (PHOTONET) created in 2015, and of the OpenLab “PhOVeA” (Photonics and Optoelectronics for Vehicle and Automotive), a common research structure with PSA.

She has authored and co-authored more than 185 international publications and communications, including 13 invited talks in international conferences, and 20 patents.

She also has given training courses since 2003 on Photonics Integration and on Plasmonics for master students and for continuous training.
