Case Library
One-click access to 11 built-in thin-film and emitting-device examples
This guide introduces Case Library, which loads built-in thin-film and emitting-device models. Use a complete case to inspect its structure, optics, Sweep, and Optimizer configuration.
Dialog Layout
| Region | Purpose |
|---|---|
| Left category list | Filter cases by type: All Cases / AR Coatings / Mirrors / Filters / LED / Special |
| Center card grid | Thumbnails, names, and one-line summaries for the cases in the active category |
| Right detail panel | Full description, highlight list, and Open Case button for the selected case |
Open Case triggers a confirmation dialog and then replaces the entire current model. The current structure, optics, sweep, and optimizer configuration are overwritten; the local autosave draft remains in the browser and can be restored via the case-comparison workflow.
Case Inventory
| ID | Name | Category | Highlights |
|---|---|---|---|
dbr-mirror | DBR Mirror @ 633 nm | Mirror | 8 pairs of TiO₂ / SiO₂ quarter-wave layers; reflection peak at 633 nm with side ripples; Phase / GD dispersion detectors enabled by default |
single-layer-ar | Single-layer MgF₂ AR @ 550 nm | AR Coating | Textbook single-layer AR; V-shaped reflectance dip; angle-dependent shift |
v-coat-ar | V-coat AR @ 550 nm | AR Coating | Al₂O₃ + MgF₂ two-layer AR; deeper V-dip than single-layer |
broadband-ar | Broadband 3-layer AR | AR Coating | MgF₂ / ZrO₂ / Al₂O₃ broadband AR; flat low reflectance across the visible |
bandpass-filter | Fabry-Pérot Bandpass @ 550 nm | Filter | DBR · half-wave cavity · DBR sandwich; narrow transmission peak |
hot-mirror | Hot Mirror | Filter | Visible-pass, NIR-reflect; common in lighting and projector heat management |
cold-mirror | Cold Mirror | Filter | Visible-reflect, IR-pass; used to extract IR heat from light sources |
solar-stack | a-Si Solar Cell | Special | ITO + amorphous-silicon absorber + glass substrate; inspect layer absorption |
beam-splitter | 50/50 Beam Splitter @ 633 nm | Special | Three-layer dielectric splitter; close to R = T = 0.5 at 45° incidence |
oled-bottom-emitting | Bottom-emitting OLED | LED | ITO / NPB / Alq3 EML / BPhen / LiF / Al; all three Emission detectors configured; BPhen-thickness sweep for weak-cavity behavior |
oled-top-emitting | Top-emitting OLED | LED | Semitransparent Ag / BPhen / Alq3 EML / NPB / Al reflector; all three Emission detectors configured; Ag-thickness sweep for strong-cavity/outcoupling trade-offs |
DBR Mirror @ 633 nm is the default case loaded on first launch.
Loading Flow
- Click the
Case Librarybutton in the top toolbar. - Pick a category on the left, or keep
All Cases. - Choose a case in the card grid.
- Read the right-side highlights to confirm the structure matches your intent.
- Click
Open Case→ confirmation dialog →Replace. - After loading, the app navigates to
Structureso you can edit or run immediately.
The Sweep and Optimizer configurations are not placeholders. Each case ships with sweep parameters and optimization goals that match its physics.
Run Sweep or Run Optimizer produces meaningful results immediately.Cases and Learning Paths
| Learning goal | Recommended cases |
|---|---|
| Interference and quarter-wave stacks | dbr-mirror |
| Single-layer AR and angle dependence | single-layer-ar |
| Compare single / double / multilayer AR performance | single-layer-ar → v-coat-ar → broadband-ar |
| Fabry-Pérot cavity filter | bandpass-filter |
| Hot vs. cold light separation | hot-mirror and cold-mirror |
| Energy distribution inside an absorber | solar-stack (with Layer Absorption and depth detectors) |
| Polarization-dependent splitting | beam-splitter |
| Introductory OLED emission and mode-loss analysis | oled-bottom-emitting |
| Microcavity effects on spectrum, angular distribution, and LEE/EQE | oled-top-emitting |
Relationship to Local Data
Loading a case only replaces the model snapshot in the Pinia store. It does not clear:
- Refractive index files already imported into the browser (
Databasemode still works); - Imported incident spectrum files;
- User preferences and performance thresholds in
Settings; - History entries in
Logs.
If you want to keep your current model before loading a case, click the export button in the toolbar (pi pi-download) first to save it as a .tmm.json file. See Model File Import / Export.
