Not Accessible

Your library or personal account may give you access

Abstract

A machine learning-based model was trained on beam propagation simulation data of a femtosecond laser direct written 1-D waveguide array structure with varying refractive indices, to predict the refractive index difference of laser-induced waveguide.
