      Hi I am working on Grating Coupler design. I saw a video on youtube, in that a video, a guy uses a monitor to measure refractive index of two adjacent grating regions. Using these two grating regions, he gets refractive index and calculated avg effective index for grating design. Please help me to get effective index of two adjacent regions in lumerical?

      Hello,

      An index monitor can be used to determine the refractive index in FDTD: https://optics.ansys.com/hc/en-us/articles/360034383134

      You might find these grating coupler examples useful as well:
