Hi, I'm doing a design of a photonic crystal coupler. In nanometer scale of 17X21 dimensions. I need to generate the graph of the transmission in the consol. how do I do that? Can someone help me? Thank you very much in advance.
Hi!
You can define port BC for each head/tail of PC coupler, then you'll have S-Parameters according to the where you inject EM waves. Transmission and reflection coefficient can be defined in the terms of these parameters. Here is an example...
Port 1= input and Port 2=Output, transmittance and reflectance can be expressed as,
T=abs(S21)^2 , R=abs(S11)^2
thanks
Now you can help me with the band gap e
And the index of nonlinear refraction in relation to power?
Hi!
You can follow the link for further information about band-gap analysis of photonic crystal.
