Ansys Lumerical STACK
Optical Thin-Film Simulation Software

Ansys Lumerical STACK is an optical multilayer simulator ideal for rapidly analyzing thin film multilayer stacks for anti-reflection coatings, filters, OLEDs and VCSELs.


Rapid Analysis of Thin Film Stacks with Lumerical STACK

Design thin film stacks quickly with Lumerical STACK. By utilizing analytical methods, STACK is faster than direct simulations of Maxwell’s equations. The variety of thin film simulation software functions accurately capture interference and microactivity effects under both plane- wave and dipole illumination.

Ansys Lumerical’s Component Level Tools

This webinar will start with an overview of the broad set of component level solvers it offers with an emphasis on FDTD and MODE. It will then show how these solvers can be used to simulate and optimize novel designs in a wide range of applications including micro-LEDs, augmented reality, magneto-optics and lasers.

Versatility Through Rapid Analysis of Thin Film Multilayer Stacks

Develop thin film multilayer stacks with Lumerical STACK. STACK captures microcavity effects and interference while allowing you interoperability via scripting. With dipole illumination and plane-wave functions, you can quickly analyze anti-reflection coatings, filters, OLEDs and VCSELs, all faster than direct simulations of Maxwell’s equations. The power of Lumerical STACK makes it an ideal solution for rapid prototyping for thin film applications while building, running and controlling simulations.

Key Features

From capturing microcavity effects and interference to handling dipole illumination and plane wave functions, STACK provides quick simulations of complex thin film multilayer stacks.

  • STACK Analytic Solver
  • Interoperability via Scripting

The STACK Analytic solver is faster than direct simulation of Maxwell’s equations. It is ideal for rapid prototyping for thin film applications and functions are available for both plane-wave and dipole illumination. The solver captures interference and microcavity effects.

Lumerical STACK tools are interoperable through the Lumerical scripting language, Automation API and Python and MATLAB APIs.



In this example, we use the STACK optical solver and FDTD to characterize a cylindrical micro-LED and extract the emitted power and radiation pattern


Polarization-sensitive plasmonic reflectors for HUD – Speos Interoperability

For a HUD that needs to reflect polarized lights, here we demonstrate periodic plasmonic nanostructures that could provide significant reflection for certain polarization.


Interfacing with ZEMAX - OLED example

In this example, we show how to use both Lumerical's Stack Optical Solver for planar OLEDs and FDTD for patterned OLEDs to generate a ray set that can be used to study the incoherent emission from a macroscopic device in Zemax OpticStudio.


STACK Product Reference Manual

The STACK reference manual provides detailed descriptions of product features.



Using Lumerical’s PID flow on AWS EC2, new SiPh grating couplers were developed with a footprint 20x smaller than CompoundTek’s existing coupler and with predicted improvements in performance.
