Changing Optical Design: How Multi scale Simulation Improves the Efficiency of Modern Devices

Optical equipment is an integral part of technologies such as data centers and autonomous vehicle, which are constantly developing to meet the needs of complex applications. The challenge faced by designers is to manipulate light at the wavelength scale to achieve the required optical properties, which requires precision at both the nano and macro scales. Nanoscale structures, such as those on LEDs, improve efficiency through photonic crystals and require designers to perform high-precision simulations at different scales.

In 2021, Ansys' acquisition of Zemax marked an important step in addressing the challenges of optical device design. This merger combines Zemax's OpticStudio with Ansys's integrated platform, which is renowned for analyzing light interactions greater than wavelength. This platform enables designers to conduct visual simulations from the nanoscale to the system level, ensuring the efficiency and accuracy of developing modern optical systems.

Ansys Lumerical simulates the interaction between light and wavelength scale structures by solving Maxwell's equations, which is a key function in designing efficient nanostructures on LEDs. Meanwhile, Ansys Speos provides system level visualization and validation, integrating human visual acuity into simulations. This is particularly important for applications such as car headlights and AR/VR head mounted devices, where understanding human perception can greatly reduce the need for expensive physical prototypes.

The integration of OpticStudio, Lumerical, and Speos on the Ansys platform represents a leap in optical design and simulation. Nowadays, design engineers can use multi physical fields and multi-scale simulation toolkits to develop optical products with unprecedented efficiency and accuracy. This progress demonstrates our continuous efforts to provide seamless and user-friendly interfaces to connect these complex solutions, enabling engineers to quickly bring innovative optical systems to the market.

The collaboration between Ansys and Zemax is backed by cutting-edge simulation technology, setting new standards for the design and modeling of modern optical devices. By implementing full spectrum simulation from nanostructures to system level applications, this platform not only improves the efficiency and performance of optical devices, but also drives innovation in fields that heavily rely on advanced optical technology.
