refractive index vs Wavelength curve

    • RezaJalali

      Hi Everyone,

      I hope you are doing well.

      I would like to plot the refractive index vs Wavelength curve (dispersion curve). I have used an index monitor to see it. but when I modify some parameters of my design(ring resonator) the curve does not change! for example, when I change the waveguides' sidewall angle it seems on no effect on the curve!

      I attach the curve which I derived for any sidewall angles!

      Thank you.

      The change of the refractive index depends on the radius of curvature and the bandwidth of the wavelength. Once you found a significant change of refractive index at the given radius of curvature at a given wavelength, you can sweep a little wider wavelength range. Make sure the the "bent waveguide" is selected. Please try and let us know if it works for you.
