  • HW-1

    Using tidy3D interface design a SiN/SiOx - air cladding waveguide/substrate structure with h=500 nm, and variable width 1.55 um. Locate widths support only TE, and two TE, three TE modes. Report neff and plot E, and transverse Electric Field component.

  • HW-2

    Using Lumerical MODE design a SiN/SiOx - air cladding waveguide/substrate structure with h=500 nm, w=1000 nm at 1.55 um. Create a copy of this waveguide with same height and y-dimensions. Change the seperation between the waveguides from 0 to 200 nm with 20 nm steps and plot the E-field intensity and comment on the E-field distribution. Similarly plot efective index values for different geometries in a single plot and comment.
