Liquid crystals (LC) offer numerous prospects in photonics, for instance, nematics LC-based electro-optical devices enables tunable phase-shifting of optical and THz radiations, or phase-sensing. Indium-Tin-Oxide (ITO) is one of the most employed ele

The measurement of extremely small displacements is of utmost importance, both for fundamental studies [1-4], and practical applications [5-7]. One way to estimate a small displacement is to measure the Doppler shift generated in light reflected off

Adaptive holography for optical sensing applications

Autor: Arnaud Peigné, Stephanie Molin, U. Bortolozzo, Pascale Nouchi, Daniel Dolfi, S. Residori, J. P. Huignard

Publikováno v: Slow Light, Fast Light, and Opto-Atomic Precision Metrology IX.

Adaptive holography is a promising method for high sensitivity phase modulation measurements in the presence of slow perturbations from the environment. The technique is based on the use of a nonlinear recombining medium, here an optically addressed

Adaptive interferometry for high sensitivity optical fiber sensing

Autor: S. Residori, A. Peigné, Stephanie Molin, U. Bortolozzo, J. P. Huignard, Daniel Dolfi

Publikováno v: SPIE Proceedings.

We report on the use of an adaptive holographic interferometer, based on a liquid crystal light valve, to achieve phase shift measurements in an optical fiber. Owing to the physical mechanisms involved, the interferometer adapts itself to slow phase
