Density of states, photonic crystal

[Laplas]

Hello!
I know how to calculate band structure and density of states of photonic crystal (example is pic.1)

Does anybody know how to plot such DOS maps?

The second picture is from the article about photonic crystal fibers by Rodrigo Amezcua.

The expression "heat map", e.g. from gnuplot, cimes to my mind.

Ok.
But it is the density of states of a photonic crystal. May be you know how to plot it like on the picture 2?

If this is a question how to produce this kind of coloured plot of a function of two variables, then I think I already provided an answer. Or do you mean how to calculate the DOS as a function of $n_{eff}$ and $\lambda/\Lambda$, which I could be of little help?

I mean how to calculate the DOS as a function of neff and λ/Λ.

I would be grateful if you can help me.

Do you have a proper citation for the article this is from?

 

[Laplas]

Sure.

Isn't this more of a question on how one plots a contour map, i.e. a software question? Considering that you claim that you know how to calculate the DOS, it means that you already have the necessary data to be plotted. From what I can understand, that leaves the question on how you plot that data.

Or am I missing something?

I can't follow these links you provided.

Sorry. Here they are.

I don`t know how to calculate the DOS as a function of neff and λ/Λ.
