Analysis of birefringence in magneto-optical waveguides based on nanoparticles doped sol–gel matrix with an optimized substrate
Source abstract
Abstract
Abstract The elimination of birefringence remains a key challenge in integrated optical systems. In this work, we present birefringence study based on the controlling of layer thickness of planar waveguides, using deposited layers based on magnetic nanoparticles. The birefringence can be reduced with a planar device, depending on a glass substrate. The simulation carried out by MATLAB allowed us to deduce the conditions to decrease the phase mismatch and increase the conversion ratio of modes.
