waveguide taper design varFDTD simulation-Duplicate

    • Shashank Gupta

      Hello Sir,

      I am following the curved waveguide taper example " https://optics.ansys.com/hc/en-us/articles/360042799713-Curved-waveguide-taper-varFDTD-and-FDTD- " for taper design for my material.

      The gaussian source defined in the exampler uses 'use thin lens' method in the beam option setting. I am unable to understand how the beam option parameters (NA, lens diameter, beam diameter, etc) is defined ?

      I think it depends on the effective refractive index. If so then how to decide these values for different refractive index (neff for my material is 1.91).

      Also, boundary condition in varFDTD uses 'uniaxial anisotropic PML' setting. How to define these parameters?

      Thanks
