  author={Boyuan Jin and Christos Argyropoulos},
Nonreciprocal transmission is the fundamental process behind unidirectional wave propagation phenomena. In our work, a compact and practical parity-time (PT) symmetric metamaterial is designed based on two Silicon Carbide (SiC) media separated by an air gap and photonically doped with gain and loss defects. We demonstrate that an exceptional point (EP) is formed in this PT-symmetric system when SiC operates as a practical epsilon-near-zero (ENZ) material and by taking into account its moderate… 



Nonreciprocal Transmission in Nonlinear PT‐Symmetric Metamaterials Using Epsilon‐Near‐Zero Media Doped with Defects

Nonreciprocal transmission forms the basic operation mechanism of optical diodes and isolators and requires the tantalizing task of breaking the Lorentz reciprocity law. In this work, strong

Experimental demonstration of broadband Lorentz non-reciprocity in an integrable photonic architecture based on Mach-Zehnder modulators.

This work demonstrates the first active optical isolator and circulator implemented in a linear and reciprocal material platform using commercial Mach-Zehnder modulators, and provides a practical answer to the challenge of non-reciprocal light routing in photonic integrated circuits.

Design of zero index metamaterials with PT symmetry using epsilon-near-zero media with defects

Inspired by the design of matched zero-index metamaterials (ZIMs) using defects in epsilon-near-zero (ENZ) media, we demonstrate in this letter that ZIMs with parity-time (PT) symmetry in a waveguide

Role of epsilon-near-zero substrates in the optical response of plasmonic antennas

Radiation patterns and the resonance wavelength of a plasmonic antenna are significantly influenced by its local environment, particularly its substrate. Here, we experimentally explore the role of

Loss-compensated broadband epsilon-near-zero metamaterials with gain media

The concept of loss-compensated broadband epsilon-near-zero metamaterials consisting of step-like metal-dielectric multilayer structures doped with gain media is proposed based on the combination of

Microresonator Isolators and Circulators Based on the Intrinsic Nonreciprocity of the Kerr Effect

Nonreciprocal light propagation is important in many applications, ranging from optical telecommunications to integrated photonics. A simple way to achieve optical nonreciprocity is to use the

Broadband passive isolators based on coupled nonlinear resonances

Isolators are devices that transmit waves only in one direction, and are widely used to protect sensitive equipment from reflections and interference. These devices inherently require the breaking of

Gain assisted propagation of surface plasmon polaritons on planar metallic waveguides.

It is shown that the presence of the gain medium can compensate for the absorption losses in the metal and suggest that lossless gainassisted surface plasmon polariton propagation can be achieved in practice.

Passive all-optical diode using asymmetric nonlinear absorption

Saturable and reverse saturable absorptions are well-known phenomena, originating from the imaginary component of the third order nonlinear optical susceptibility. We note that structures with an

Low-loss, infrared and terahertz nanophotonics using surface phonon polaritons

Abstract The excitation of surface-phonon-polariton (SPhP) modes in polar dielectric crystals and the associated new developments in the field of SPhPs are reviewed. The emphasis of this work is on
