FIELD: fiber optic communication systems; data processing.
SUBSTANCE: in the device of the polarization converter, a waveguide in the form of an ellipse is used, a part of the surface above which is covered with a dielectric layer with a refractive index equal to that of the substrate. In the part of the surface above the waveguide where the film is absent, the cover area is air. Film is located at an angle relative to the longitudinal geometric axis of the waveguide. This design allows not to rotate the cross-sectional shape of the channel itself along the z axis, smoothly varying the distribution of the refractive index of the coating medium along the x axis along the waveguide.
EFFECT: when using the design of an integrated optical polarization converter, it is possible to convert linear polarization of radiation into circular with low loss of optical radiation and simplify the manufacturing technology of the optical scheme.
