We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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!
