A WDM/DWDM model for AWGs and Echelle Gratings
What is Epipprop?
Epipprop is a unique and innovative tool for the modelling and optimisation of:
in particular for wavelength division multiplexing applications (WDM/DWDM).
Epipprop derives from the Greek word επίπεδο or “epipeda” which means layer or plane. Epipprop is a tool for simulating WDM devices that include a wide dielectric layer where a beam of light is confined vertically but is free to expand over large distances laterally – a geometry seen in the star couplers of AWGs and in planar Echelle gratings or planar concave gratings. Epipprop has efficient numerical techniques for modelling such wide layers – much more efficient than traditional techniques like BPM.

Echelle Gratings and Planar Concave Gratings
Echelle gratings provide a very efficient method for wavelength de-multiplexing (WDM) with a small footprint: they are typically much smaller than arrayed waveguide gratings (AWG) and offer simpler layouts.
Photon Design provides in Epipprop the first commercial 3D echelle grating simulation package. Using AWGs? Why not see if an echelle grating would be better!

Arrayed Waveguide Gratings
Arrayed waveguide gratings use a series of parallel waveguides of differing length to create a phase based device where light of different wavelengths are focused to a different position in space. They are widely used for wavelength de-multiplexing (WDM).
