In the first paper: It just uses the matrix but does not explain why we have the conjugate
In the second paper: The same as in the first.
In the third paper: The matrix...
Hello everyone,
A simple ring resonator with a bus waveguide is described by:
$$ \begin{pmatrix} E_{t1}\\ E_{t2} \end{pmatrix} =
\begin{pmatrix} t & k\\ -k^* & t^* \end{pmatrix}
\begin{pmatrix} E_{i1}\\ E_{i2} \end{pmatrix} $$
I do not understand though why we have -k* and t*? Shouldn't...
