Second- and higher-order waveguide grating filters. 2: experiment.
A series of careful and systematic measurements is made to determine the reflection, transmission, and radiation loss coefficients of second- and third-order waveguide grating filters, and the dependence of these coefficients on the wavelength of the incident light. The experimental measurements are found to agree very well with results of calculations made using a Green's function approach, which we have reported in the preceding paper. This shows the Green's function approach to be a reasonably simple but quite accurate method for calculating the spectral response of grating filters.
