High sensitive synchrone detection based dynamic Sénarmont method for measurements of electro-optical (EO) Pockels and Kerr coefficients in hybrid nanocomposites films.

This study introduces an innovative approach by employing a highly sensitive synchronous detection-based dynamic Sénarmont method for the precise measurement of electro-optical (EO) Pockels and Kerr coefficients within hybrid nanocomposite films. The experimental setup integrates LabVIEW instrumentation software, ensuring accurate data acquisition. The EO-active film compositions encompass diverse polymer (PMMA) and organic dye combinations, including PMMA/organic dyes (DR1 and CPO), as well as PMMA combined with DR1-SiC, DR1-TiO2, and CPO-TiO2. Through meticulous experimentation and calibration of the Sénarmont setup, this research demonstrates exceptional sensitivity in evaluating EO parameters based on film composition. Notably, the study examines the impact of poling conditions, geometric configurations, and the influence of TiO2 nanoparticle integration on electro-optical behavior. The findings reveal distinctive electro-optical responses, highlighting the significant potential for tailored designs and practical applications in optimizing polymer nanocomposite electro-optical properties. Overall, this work offers valuable insights into refining measurement techniques and leveraging nanomaterials for enhanced electro-optical functionalities.
