The growing maturity of nanofabrication has ushered massive sophisticated optical
structures available on a photonic chip. The integration of subwavelength-structured …

Nanophotonics has garnered intensive attention due to its unique capabilities in molding the
flow of light in the subwavelength regime. Metasurfaces (MSs) and photonic integrated …

Over the past few years, progress in hollow-core optical fiber technology has reduced the
attenuation of these fibers to levels comparable to those of all-solid silica-core single-mode …

Recent advances in photonic integrated circuits have enabled a new generation of
programmable Mach–Zehnder meshes (MZMs) realized by using cascaded Mach–Zehnder …

We use inverse design to discover metalens structures that exhibit broadband, achromatic
focusing across low, moderate, and high numerical apertures. We show that standard unit …

We present an adjoint-based optimization for electromagnetic design. It embeds commercial
Maxwell solvers within a steepest-descent inverse-design optimization algorithm. The …

A new class of hybrid systems that couple optical, electrical and mechanical degrees of
freedom in nanoscale devices is under development in laboratories worldwide. These nano …

This paper describes Meep, a popular free implementation of the finite-difference time-
domain (FDTD) method for simulating electromagnetism. In particular, we focus on aspects …

Plasmonic antennas enable the conversion of light from free space into subwavelength
volumes and vice versa, which facilitates the manipulation of light at the nanoscale. Dynamic …

A new class of composite materials has emerged which provides a means to control and
manipulate light. These materials, known as photonic crystals, are periodic arrays of …
