Abstract
By the example of yttrium ferrite garnet films on a nonmagnetic substrate with the plane orientation (111), the results of calculations of the changes in Stokes vector components of a polarized radiation propagating in the planar light guide at the tension-compression deformations of a sample are given. The wave vector of optical radiation, mechanical stress, and bias field are directed along the $[1\bar{1}0]$ axis. The obtained sensitivity of Stokes vector components ${dC}/{d\sigma}$ and ${dS}/{d\sigma}$ is $10^{8}$ Pa$^{-1}$ in the stress range of ±50 MPa. The calculations are made at a bias field of 600 A/m.
