Nanophotonic devices, such as metasurfaces and silicon photonic components, have been
progressively demonstrated to be efficient and versatile alternatives to their bulky …

Replacing curved and bulky optical elements with thin and lightweight counterparts is a
persistent pursuit of the optical society. Metasurfaces, as two-dimensional artificial …

Structured light, also known as tailored light, shaped light, sculpted light, or custom light,
refers to a series of special light beams with spatially variant amplitudes and phases …

A key idea in many-objective optimization is to approximate the optimal Pareto front using a
set of representative non-dominated solutions. The produced solution set should be close to …

We introduce the concept of meta-learning into the design of active optical switches. An
optical switch consists of both tunable and nontunable elements. It has been difficult to apply …

We numerically demonstrate the inverse design of a structure for free-space beam steering,
based on twisted bilayer photonic crystal slabs. The structure consists of two photonic crystal …

Recent developments in the computational automated design of electromagnetic devices,
otherwise known as inverse design, have significantly enhanced the design process for …

The concept of metamaterials offers a flexible pathway to manipulate the macroscopic
behavior of light by delicately designed microscopic subwavelength structures, which has …

The development and optimization of photonic devices and various other nanostructure
electromagnetic devices present a computationally intensive task. Much optimization relies …

In this work, we demonstrate a compact toolkit of inverse-designed, topologically optimized
silicon photonic devices that are arranged in a “plug-and-play” fashion to realize many …
