Features
EPIPPROP Features
- 3D fully vectorial modelling of echelle gratings and AWGs with Epipprop
- Selection 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 them
- Use 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!
