Abstract

Meta Studio is an AI-powered metalens design automation platform that streamlines the design process for metasurface devices. By integrating advanced phase design, meta-atom optimization, and field propagation simulation into one intuitive workflow, Meta Studio enables rapid prototyping and design of high-performance optics. This white paper introduces Meta Studio's key capabilities and showcases application examples including metalens design.

Introduction

Photonic devices like lenses, waveguides, and holograms formed by metasurfaces are enabling breakthroughs in augmented reality, LiDAR, quantum computing, and more. However, designing these nanophotonic structures remains difficult and time-consuming due to the complex physics involved. Meta Studio tackles this challenge by combining artificial intelligence with physics-based electromagnetic simulation.

Meta Studio's automated workflow guides users through metasurface design in three simple steps:

  1. Phase Design: Users specify optical parameters like wavelength, focal length, and meta-atom size. Meta Studio's AI engine then generates the required phase profile.

  2. Meta-Atom Optimization: Meta Studio optimizes the shape and dimensions of meta-atoms to achieve the target phase delays. The AI learns from past designs to accelerate optimization.

  3. Simulation & Analysis: Full-wave solvers predict the optical performance. Advanced visualization tools plot field distributions and ray tracing.

With Meta Studio, designers bypass tedious manual calculations and simulations. The AI assistant handles the complex physics, while designers focus on specifying optics requirements. By automating time-consuming tasks like topology optimization and EM simulations, Meta Studio cuts project timelines from months to days.

Applications

Meta Studio's flexible workflow enables designing diverse metasurface devices, from metalenses to vortex beam generators. Some application examples include:

Metalenses: Meta Studio can design dual-polarity hyperbolic lenses, achromatic lenses, and aspheric lenses. The platform optimizes for diffraction-limited focusing and high numerical aperture.


Metalenses

Wavefront manipulation: Users can specify custom phase profiles to shape wavefronts. This enables designing unconventional optics like Airy beams and optical vortices.


Wavefront manipulation

Holograms: Meta Studio can iteratively design metasurface holograms by calculating the required interference patterns. This allows reconstructing high-fidelity 3D images.


Holograms

Beam steering: Dynamic metasurfaces with tunable meta-atoms allow beam steering for LiDAR and free-space communications. Meta Studio helps design efficient phase shifters.

The platform also exports designed devices as GDSII layouts for further simulation and fabrication. Meta Studio is valuable for both research and commercial photonics teams looking to accelerate prototyping.

Conclusion

Meta Studio addresses key pain points in metasurface design through its user-friendly workflow and AI assistant. By automating time-intensive EM simulations and topology optimization, the platform boosts designer productivity. Meta Studio allows rapid iteration to realize novel flat optics and quantum photonic devices. Looking ahead, enhancing the AI engine and adding more advanced design features will help democratize nanophotonics.
