Photonic processors that can perform arbitrary tasks are in demand for many applications. Here, the authors present a photonic architecture using waveguide and resonator couplings to perform arbitrary linear transformations, by taking advantage of th

The local Drude model predicts that, under certain conditions, surface plasmon polaritons at a metal-dielectric surface have a frequency range where only unidirectional propagation is supported. Here, the authors show that in more realistic non-local

We report on time–frequency analysis (TFA) of dispersion in a 1-D magneto-inductive waveguide (MIW). The short-time Fourier transform (STFT) and Wigner–Ville distribution (WVD) are used to localize the frequency content of the dispersed wave as a

In the presence of an external magnetic field, the surface plasmon polariton that exists at the metal-dielectric interface is believed to support a unidirectional frequency range near the surface plasmon frequency, where the surface plasmon polariton

We introduce a new method for inverse design of nanophotonic devices which guarantees that resulting designs satisfy strict length scale constraints - including minimum width and spacing constraints required by commercial semiconductor foundries. The

In many optical systems, such as metal films, dielectric reflectors, and photonic crystals, electromagnetic waves experience evanescent decay. The spatial length scale of such a decay defines the p...

Arbitrary linear transformations are central to photonic quantum information processing and machine learning. We present a photonic architecture of time-modulated micro-ring resonators with tunable couplings between frequency modes to achieve arbitra
