This element is used to model routing waveguides that have back annotation with third party tools. The geometry-specific waveguide properties of a routing waveguide are communicated between a third party tool (where the waveguide geometry is defined in layout) and the compact model in INTERCONNECT.

Data Table |
A data table in specific format containing effective index, group index, loss and dispersion as a function of wavelength, waveguide width, curvature, temperature and mode type. See wg_back_annotation_table_example.txt file lumfoundry/source/wg_back_annotation for an example of the table data format needed for this element. Note: This table must be provided to the third party software and is not used directly by the CML Compiler. |
