====================================
Implementation Details
This Optical Modulator Lookup Table element has the similar concept as the electrical Lookup Table element and it is a reciprocal element. This element is especially useful when defining laser LI properties. In the example file optical_modulator_lookup_table_example.icp, a laser LI file LI_mA.txt is loaded to the Optical Modulator Lookup Table element. The LI curve is showing below:
The design schematic is shown below. With two different inputs at each end, the output power spectrum diagrams are plotted in the following figures.
