Abstract: (5724 Views)
Topological polarization behavior of the optical guided mode in a Ti indiffused Lithium Niobate (Ti:LiNbO3) waveguide is investigated theoretically. It is revealed the azimuth change of the state of the polarization for e.g. fundamental guided mode. Ti indiffusion causes a different slope of increase for the ordinary (no) and extraordinary (ne) refractive indices. Such a difference induces spatial birefringence in the plane perpendicular to the propagation direction. Therefore the state of the polarization will change in the plane where the guided mode spatially is located. Results indicate increase in the rate of change of polarization state as radial and azimuthal in the propagation direction.
