Degradation of modulation and noise characteristics of semiconductor lasers after propagation in optical fiber due to a phase-shift induced by stimulated Brillouin scattering [PDF]
, 1999 Here we demonstrate theoretically that stimulated Brillouin scattering (SBS) can induce a phase shift of the optical carrier relative to its sidebands due to the waveguiding effect of the optical fiber on the acoustic wave.

Rayleigh Fading Suppression in One-Dimensional Optical Scatters
IEEE Access, 2019 A highly coherent wave is favorable for applications in which phase retrieval is necessary, yet a high-coherence wave is prone to encounter Rayleigh fading phenomenon as it passes through a medium of random scatters.

Multiscale Modeling of Process‐Induced Defects in Fused Filament Fabrication‐Printed Materials
Advanced Engineering Materials, EarlyView.This study presents a predictive multiscale modeling tool for defect analysis of fused filament fabricated‐printed materials and their performance prediction using a mechanistic data science‐based reduced‐order modeling approach. Process‐induced defects are inherent to additively manufactured parts and significantly influence the performance of printed
