³ Right stopband: indicates the spectral position difference between
the main mode and the closest side-mode on the right.
³ Two-sided stopband: indicates the spectral position difference
between closest left and right side-modes adjacent to the main mode.
³ Central offset: indicates the spectral position of the main mode minus
the mean of the spectral positions of the first adjacent left and right
side-modes.
³ Fabry-Perot mode spacing: indicates the average estimated spectral
spacing between adjacent Fabry-Perot modes of the DFB.
