Metalens Enhanced Ray Optics: An End-to-End Wave-Ray Co-Optimization Framework
Ziwei Zhu, Zhaocheng Liu, Changxi Zheng
We present a fully differentiable framework for seamlessly integrating wave optical components with geometrical lenses, offering an approach to enhance the performance of large-sca…
Hypersphere Optimization: Approximated Gradient-Based Binary Optimization on Smooth Manifold for Photonic Inverse Design
Zhaocheng Liu
Photonic inverse design typically seeks designs parameterized by binary arrays, where the values of each element correspond to the presence or absence of material at a particular p…
A topological encoding method for data-driven photonics inverse design
Zhaocheng Liu, Zhaoming Zhu, Wenshan Cai
Data-driven approaches have been proposed as effective strategies for the inverse design and optimization of photonic structures in recent years. In order to assist data-driven met…
Compounding meta-atoms into meta-molecules with hybrid artificial intelligence techniques
Zhaocheng Liu, Dayu Zhu, Kyu-Tae Lee +3
Molecules composed of atoms exhibit properties not inherent to their constituent atoms. Similarly, meta-molecules consisting of multiple meta-atoms possess emerging features that t…
A Hybrid Strategy for the Discovery and Design of Photonic Nanostructures
Zhaocheng Liu, Lakshmi Raju, Dayu Zhu +1
Designing complex physical systems, including photonic structures, is typically a tedious trial-and-error process that requires extensive simulations with iterative sweeps in multi…
A Generative Model for Inverse Design of Metamaterials
Zhaocheng Liu, Dayu Zhu, Sean P. Rodrigues +2
The advent of two-dimensional metamaterials in recent years has ushered in a revolutionary means to manipulate the behavior of light on the nanoscale. The effective parameters of t…
