1) I meant for large oxide aperture of a VCSEL there may 2 modes having slightly different effective refractive index ,due to distinctively different in-plane/transverse characteristics but very close frequency as seen from resonance finder.   Following this example and photonic crystal cavity example, i found this frequencies of modes by resonance finder. But in 2nd simulation when I put a frequency domain field profile monitor at this frequencies, I find the in-plane shape is same. How do I get the correct in-plane spatial distribution for these modes?

 

2) What is webpage/email to subscribe to premium support? Is it directly from Lumerical or through an external channel partner?
