A WDM/DWDM model for AWGs and Echelle Gratings

AWG Model

In addition to the standard features of Epipprop's model, our AWG model includes the following features:

  • Tunable grating templates for AWGs.

  • Simple parameterised design: choose wavelength, diffraction order, waveguide geometry, mode of operation and number of waveguides and let Epipprop create the arrayed waveguide paths.

  • Space output waveguide channels by wavelength and frequency.

  • Model the effect of material loss and scattering loss in the array of waveguides.

  • Simulate simple adiabatic tapered structures on AWG to free propagation region interface.
