This review focuses on the optical properties and device applications of deterministic
aperiodic media generated by mathematical rules with spectral features that interpolate in a …

Subwavelength dielectric resonators assembled into metasurfaces have become a versatile
tool for miniaturizing optical components approaching the nanoscale,–. An important class of …

We show that nonlinear optical structures involving a balanced gain-loss profile can act as
unidirectional optical valves. This is made possible by exploiting the interplay between the …

Optical diodes controlling the flow of light are of principal significance for optical information
processing. They transmit light from an input to an output, but not in the reverse direction …

We demonstrate the possibility of optical nonreciprocal response in a three-mode
optomechanical system where one mechanical mode is optomechanically coupled to two …

A mechanism for asymmetric transport which is based on parity-time-symmetric
nonlinearities is presented. We show that in contrast to the case of conservative …

In this work we consider the role of aperiodic order—order without periodicity—in the design
of different optical devices in one, two and three dimensions. To this end, we will first study …

We propose to demonstrate nonreciprocal conversion between microwave and optical
photons in an electro-optomechanical system where a microwave mode and an optical …

The semiconductor diode, which acts as an electrical rectifier and allows unidirectional
electronic transports, is the key to information processing in integrated circuits. Analogously …

Light propagation in asymmetric Kerr-nonlinear multilayers with perfect transmission
resonances is theoretically investigated. It is found that hybrid Fabry-Perot-resonator …
