An overview is presented of the current state‐of‐the‐art in silicon nanophotonic ring
resonators. Basic theory of ring resonators is discussed, and applied to the peculiarities of …

Toroidal moments in artificial media have received growing attention and considered as a
promising framework for initiating novel approaches to manage intrinsic radiative losses in …

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 …

Surface waves in topological states of quantum matter exhibit unique protection from
backscattering induced by disorders, making them ideal carriers for both classical and …

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 …

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 …

Optical resonators manifest themselves everyday in our world: from the lasers in
supermarket scanners to the colorful patterns reflected from oil slicks. They all share the …

We demonstrate theoretically the existence of one-way electromagnetic modes in a
waveguide formed between a semi-infinite photonic crystal structure and a semi-infinite …

Topological phononic states, which facilitate unique acoustic transport around defects and
disorders, have significantly revolutionized our scientific cognition of acoustic systems. Here …

The unique ability of slot and sub-wavelength grating (SWG) waveguides to confine light
outside of the waveguide core material has attracted significant interest in their application to …
