Multiple Detectors

Leda provides multiple detectors for comprehensive optical analysis

Multiple detectors can simulate spectrum, angular distribution, optical loss channel, etc. The combination of multiple detectors can deeply explore the optical mechanism and comprehensively optimize the device.

Angular Spectrum

Emission spectrum and angular intensity distribution.
Power Dissipation

Power dissipation density per unit in-plane wave vector.
Mode Distribution

Power coupled to different optical channels, and Purcell factor.

Research on Optics

01. Microcavity Effect ― Combining the three detectors, you can explore the impact of microcavity effect on spectrum, angular intensity distribution, waveguide loss, and outcoupling efﬁciency.
02. Purcell Effect ― The Purcell effect describes the enhancement of the spontaneous emission rate by a confined environment, it can be explored with the mode distribution detector.
03. Waveguide ― Waveguide modes are optical losses due to total internal reflection. Using power dissipation and mode distribution detectors to study waveguide modes can help design light extraction structures.
04. Surface Plasmon Polariton ― Surface plasmon polaritons at a metal-dielectric interface are optical losses. Power dissipation and mode distribution detectors can help analyze and find solutions to reduce it.

Angular Spectrum

Angular intensity distribution under microcavity effect

A semitransparent metallic electrode is used to enhance microcavity effect, and the angular intensity distribution varies with wavelength.

Power dissipation

Power dissipation spectrum

Power dissipation spectrum reveals the resonant peak shift with varied wavelength. You can switch polarization and detector direction in the result.

Mode Distribution

Outcoupling efficiency with varied HTL and ETL thicknesses

Hole transport layer (HTL) and electron transport layer (ETL) thicknesses determine the microcavity, which can be used to optimize the outcoupling efficiency.

Parameter Sweep

Sweep parameters to optimize efficiency

01. Double Parameter Sweep ― Sweep supports up to two parameters. Results can be presented as line charts and heatmaps.
02. Support for structure, emitters ― Sweep layer thickness and refractive index, emitter position and quantum efficiency, etc.
