Entry point for published Propagation and Emission case reproductions
This page groups device cases that can be reproduced from published paper parameters by Propagation and Emission simulation. Each article provides the structure, optical settings, sweep or optimization configuration, and a comparison with the paper's figures.
The Emission cases are ordered as top-emitting micro-OLED, top-emitting QLED, and microcavity PeLED for sequential reading.
Propagation Simulation
| Case | Main detectors | Role of the optical simulation in the original paper |
|---|---|---|
| Omnidirectional Reflector | Reflectance | Proved that a dielectric multilayer can stay highly reflective at every incident angle and for both polarizations, and located the edges of the reflection band |
| Ultrathin Absorbing Coatings | Reflection Spectrum, Reflection Color | Explained why a strongly absorbing film only tens of nanometers thick produces pronounced interference color, and predicted the thickness-to-color mapping |
Emission Simulation
| Case | Main detectors | Role of the optical simulation in the original paper |
|---|---|---|
| One-Dimensional Microcavity Thickness Optimization in a Top-Emitting Micro-OLED | Power Dissipation, Mode | Reproduced the internal angular power distribution and three single-layer thickness sweeps, then compared top outcoupling, waveguide, evanescent, and absorption power channel by channel |
| Top-Emitting QLED Outcoupling | Mode, Power Dissipation | Calculates bottom- and top-emitting mode partition and analyzes how the two IZO thicknesses affect EQE/γ, waveguide power, and evanescent power |
| Microcavity PeLED Angular Emission | Intensity | Compares a top-emitting and a bottom-emitting device: the cavity shifts the top-emitting spectrum with angle, while the bottom-emitting spectrum stays fixed and its angular profile is close to Lambertian |
| Regular Tandem QLED Outcoupling | Mode | Accounted for the outcoupling contribution of each emitting unit in the tandem structure, showing that the doubled efficiency is not a simple sum |
| Tandem QLED Cavity Optimization | Mode | Used cavity maps to locate the optimal cavity length set by the interconnecting-layer thickness, providing the optical basis for the device design |
| SPP Mode Suppression in an Inverted Single-Layer OLED | Mode, Power Dissipation | Showed that the inverted architecture moves power out of the surface-plasmon channel, explaining the optical origin of the efficiency gain |
| Anisotropic OLED Outcoupling | Mode, Power Dissipation, Intensity | The simulation method is the subject of the paper itself: it establishes an outcoupling calculation for stratified anisotropic OLEDs and uses it to separate the effects of dipole orientation and transport-layer birefringence |
| Optical Power Distribution in Graphene OLEDs | Mode | Showed how optical power is redistributed among the channels once the electrode and the hole-injection layer are changed |
| TEOLED Purcell-Factor Tuning with a Capping Layer | Mode | Showed that the Purcell factor must be included when optimizing the device structure, otherwise the capping-layer thickness is chosen incorrectly |
| Outcoupling and Loss Split versus OLED Emitter Position | Mode, Power Dissipation, Intensity | Broke the optical losses of an OLED down channel by channel, and located the optimal range of the emitter-to-cathode distance |
| Emission Position and Outcoupling Efficiency in a Broad-Recombination OLED | Mode | Showed in which direction the optimal emissive-layer thickness moves once the recombination zone broadens from a point into a profile |
| Cavity-Length Tuning and Angular Color Shift in Strong-Microcavity Top-Emitting OLEDs | Intensity | Identified the higher-order resonant modes of the Fabry–Pérot microcavity, and explained the angular color shift and linewidth narrowing of each order |
| Microcavity Resonance Design for Near-Infrared Phototherapy OLEDs | Intensity | Placed the resonance wavelength of the tandem microcavity in the near-infrared window required for phototherapy, deriving the cavity-mode position from the transport-layer thickness |
| Bidirectional Vertical Radiance Ratio of a Transparent Perovskite LED | Intensity, Mode | Explained the optical origin of the asymmetric top and bottom emission of a transparent device, and gave the ratio as a function of wavelength |
| Dipole Orientation and Angle-Resolved Photoluminescence of TADF Doped Films | Intensity | Recovered the transition dipole orientation of the emitters from angle-resolved photoluminescence curves, linking molecular structure to orientation |
| Host Control of Dipole Orientation in TADF Emitters | Intensity | Compared nine host materials with the same orientation-recovery procedure, judging how strongly the host controls dipole orientation |
| Recovered Dipole Orientation of a Perovskite Nanocrystal Superlattice Film | Intensity | Attributed the superlattice film's ability to exceed the outcoupling efficiency limit to dipole orientation rather than to the intrinsic emission efficiency of the material |
