Investigation of the level of uncertainty given by Brillouin light scattering


Through this paper, we strive to describe the method that allows us to give an estimate of the uncertainty. This paper aims to give an estimation of the uncertainty on the frequency peak by Brillouin Scattering Stimulation. It corresponds to the speed of phonons inside a material excited by a 532 nm wavelength laser. The guideline follows the Guide to the Expression of Uncertainty in Measurement and first estimation indicates speed of the phonons at 5% at 2 sigma.

Dr. Patrice Salzenstein holds Master of Research degree, Graduate Engineering school degree and PhD in Electronics, University of Sciences and Technologies of Lille (USTL'96). Between 1996 and 2001 he worked near Paris, France, at Thomson CSF LCR (now Thales-TRT), Alcatel Alsthom Recherche, LCIE private research laboratories. He has been working since 2001 for CNRS, a government-funded research organization under administrative authority of France's Ministry of research, at FEMTO-ST institute in Besancon, in Electronic Engineering domain. In 2010, one of his articles was featured in Electronics Letters for his participation with Czech and Swiss colleagues to the best frequency stability ever measured on a quartz crystal oscillator: 2.5×10-14 at 5 MHz. Between 2010 and 2017, his fields of interest in research were for optoelectronic resonators and oscillators for microwaves photonics applications. He is now with the Micro nano Science & Systems department of CNRS UMR 6174 FEMTO-ST.
