We review the different types of dispersion engineered photonic crystal waveguides that
have been developed for slow light applications. We introduce the group index bandwidth …

Monolithic integration of Microelectromechanical Systems (MEMS) directly within CMOS
technology offers enhanced functionality for integrated circuits (IC) and the potential …

We present a computational framework for efficient optimization-based “inverse design” of
large-area “metasurfaces”(subwavelength-patterned surfaces) for applications such as multi …

We present the design for an absorbing metamaterial (MM) with near unity absorbance A
(ω). Our structure consists of two MM resonators that couple separately to electric and …

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 …

The physical principles behind the phenomenon of slow light in photonic crystal
waveguides, as well as their practical limitations, are discussed and put into context. This …

We amalgamate two fundamental designs from distinct areas of wave control in physics, and
place them in the setting of elasticity. Graded elastic metasurfaces, so-called metawedges …

Diffractive nonlocal metasurfaces have recently opened a broad range of exciting
developments in nanophotonics research and applications, leveraging spatially extended …

The appearance of so-called exceptional points in the complex spectra of non-Hermitian
systems is often associated with phenomena that contradict our physical intuition. One …

This note is intended as a brief introduction to the theory and practice of perfectly matched
layer (PML) absorbing boundaries for wave equations, originally developed for MIT courses …
