Giving to CREOL CREOL, The College of Optics & Photonics

Seminar: "Optical interference filters: a survey and outlook" by Julien Lumeau

Friday, May 4, 2018 11:00 AM to 12:00 PM
CREOL Room 103

Julien Lumeau
Aix-Marseille Univ, CNRS, Centrale Marseille, Institut Fresnel


In this seminar, I will review the actual capabilities at Institute Fresnel and more generally in the optical thin film community, to fabricate optical interference filters that can combine several tens to several hundreds of layers in order to produce more and more complex optical functions. In particular I will present actual state-of-the-art in multilayer structures modeling and design, Virtual Deposition Process, physical vapor deposition and in-situ optical monitoring. Then I will present some recent developments in the structuring of thin film optical elements and focus on the use of thin chalcogenide layers for the production of volume diffractive optical elements.


Julien Lumeau got a M.S. and Ph.D. in Physics (major in Optics) from the Institute Fresnel, France respectively in 2001 and 2004. From 2005 to 2012, he worked at CREOL, the College of Optics at the University of Central Florida as a Faculty Research Scientist on the study of photo-thermo-refractive glasses and their use for the fabrication of Volume Bragg gratings. In 2013, he joined again the Institute Fresnel as a CNRS Senior Research Scientist, where he is currently head of the thin film research group and working on the development of innovative thin film-based optical elements. He is the authors of over 200 scientific communications including ~60 peer-reviewed publications.
