I ran a number of RCWA simulations trying to reproduce the high-Q mode at a wavelength of ~1530 nm. I fixed the wavelength in these simulations since each simulation runs for a few hours. for k=3640 I got a transmittance of 0.0988, for k=3820, I got a transmittance of 0.064, for k=4000, I got a transmittance of 0.084. 

  1. Is it fair to conclude that RCWA is not able to provide accurate results for high-Q modes?
  2. What was the highest k-value you used in your benchmark simulations?

Thank you!
