Extracting results from the MQW solver is similar to the other solvers in Lumerical Finite Element IDE. After running the MQW solver the simulation results will be returned as datasets in the results of the MQW solver object. Full definitions of the result datasets can be found on the MQW solver object page.
The result datasets can be visualized with the Visualizer tool or sent to the Script Workspace, where they can be postprocessed or exported to a data file with script commands. However, depending on how the MQW stack geometry was set up, some of the results may need to be scaled (see Scaling Results).
To visualize the simulation results from the MQW solver right click on the MQW Solver object and select Visualize > [Result to visualize]. Alternatively, the results can be extracted with the visualize script command. For more information on using the Visualizer tool please see Using the data visualizer and figure windows.
Extracting Results to the Script Workspace
To extract the simulation results from the MQW solver to the Script Workspace:
- Select the MQW Solver object. The simulation results will appear in the Result View window.
- Right click on the dataset to export and select Send to script.
Alternatively, the results can be extracted with the getresult script command.
The emission and index results are calculated for the total stack thickness, including barriers. If only quantum well thickness is of interest, excluding barriers, these results should be scaled by the factor (total length)/(total quantum well length). It is important to ensure that these results apply only to the thickness used for the calculation of the mode overlap with the gain region.
When using partitioning, there will be overlapping barriers between different partitions. In that case the emission and index results for each partition again apply to the total thickness of that partition, meaning there may be some double counting with respect to the mode overlap region thickness. To avoid this, these results can be scaled to apply to quantum wells only, or to apply to a portion of partition that does not overlap with adjacent partitions.
If the MQW stack was approximated with a single quantum well, the result should also be scaled to represent the total number of quantum wells (see the Using the Single Quantum Well Approximation section of the Setting the MQW Solver Layer and Partitions page for more information).
