Fiber Bragg Gratings Reflection Co-efficient

  1. Mar 30, 2015 #1
    I am studying fiber bragg gratings for a project. I read the couple-mode theory and came across a plot of the reflection coefficient v/s wavelength used which had a global maxima at the Bragg wavelength. The plot was drawn for a constant value of the coupling constant κ. I don't understand this assumption since the coupling constant was found to be dependent on the wavelength used in the same manuscript. So a plot with the wavelength as the independent variable, keeping the coupling co-efficient constant doesn't make sense.
