EPIPPROP 

Epipprop is a unique and innovative tool for the modelling and optimisation of AWGs (arrayed waveguide gratings) and echelle gratings and planar concave gratings in particular for wavelength division multiplexing applications (WDM/DWDM).

Features

  • 3D fully vectorial modelling of echelle gratings and AWGs with EpippropSelection of tunable grating templates
  • Ultra fast propagation in the free-space region using analytic diffraction theory
  • Built-in waveguide mode solver: fully vectorial 2D+z finite difference solver (same as FIMMWAVE’s FDM Solver)
  • I/O waveguide arrays support multi-mode waveguides and arbitrary polarisation
  • Accounts for all diffraction orders
  • Model surface roughness variations in the thickness of the slab waveguide structure in the star couplers
  • Simulate multiple vertical slab modes and the coupling between themUse our built-in material database or define your own to capture the effect of material dispersion
  • Simulate tapering and cross-coupling between adjacent waveguides (FIMMPROP required)
  • Optimise deep etch to shallow etch tapered transitions and reduce losses
  • Simulate channel broadening with Multimode Interferometer input and output with multi-section tapers (FIMMPROP required)
  • Export any design layout to a multilayer GDS-II file: from CAD to Fab in one click.
