A central aim in metamaterial research is to engineer subwavelength unit cells that give rise to desired effective-medium properties and parameters, such as a negative refractive index. Ideally one can disregard the details of the unit cell and employ the effective description instead. A popular strategy to compensate for the inevitable losses in metallic components of metamaterials is to add optical gain material. Here we study the quantum optics of such loss-compensated metamaterials at…

Quantum optical effective-medium theory for layered metamaterials
The quantum optics of metamaterials starts with the question whether the same effective-medium theories apply as in classical optics. In general the answer is negative. For active plasmonics but also
Quantum optical effective-medium theory and transformation quantum optics for metamaterials
While typically designed to manipulate classical light, metamaterials have many potential applications for quantum optics as well. We argue why a quantum optical effective-medium theory is needed. We
Nonlocal modification and quantum optical generalization of effective-medium theory for metamaterials
A well-known challenge for fabricating metamaterials is to make unit cells significantly smaller than the operating wavelength of light, so one can be sure that effective-medium theories apply. But

Channeling surface plasmon–polaritons to control their propagation direction is of the utmost importance for future optoelectronic devices. Here, we develop an effective-index method to describe and
Quantum Squeezed Light Propagation in an Optical Parity-Time (PT)-Symmetric Structure
A BSTRACT — We investigate the medium effect of a parity-time ( PT )-symmetric bilayer on the quantum optical properties of an incident squeezed light at zero temperature ( T =0 K). To do so, we use

We investigate the medium effect of the two-layer parity time (PT) symmetric on the quantum optical properties of an incident squeezed light at zero temperature. For this purpose, we calculate the

In this work we demonstrate that a Bragg Stack with a periodic gain-loss modulation can function as an Omnidirectional Mirror (OM) with complete reflection at any angle of incidence irrespective of
Quantized quasinormal-mode theory of coupled lossy and amplifying resonators
In the presence of arbitrary three-dimensional linear media with material loss and amplification, we present an electromagnetic field quantization scheme for quasinormal modes (QNMs), extending


Overcoming losses with gain in a negative refractive index metamaterial.
It is shown that appropriate placing of optically pumped laser dyes (gain) into the metamaterial structure results in a frequency band where the nonbianisotropic meetamaterial becomes amplifying and the figure of merit diverges at two distinct frequency points.
Fundamental limitations to gain enhancement in periodic media and waveguides.
It is shown that this route cannot be followed uncritically: inclusion of gain inevitably modifies the underlying dispersion law, and thereby may degrade the slow-light properties underlying the device operation and the anticipated gain enhancement itself.
Loss-free and active optical negative-index metamaterials
It is experimentally demonstrated that the incorporation of gain material in the high-local-field areas of a metamaterial makes it possible to fabricate an extremely low-loss and active optical NIM.
Experimental determination of the refractive index of metamaterials
We present a simple experimental technique based on diffraction for determining the complex refractive index of metamaterials, and demonstrate it with metamaterials that consist of detuned electrical
Low-Loss Plasmonic Metamaterials
The development of new materials for low-loss MM components and telecommunication devices is required because metals have traditionally been the material of choice for the building blocks, but they suffer from high resistive losses.

We examine some of the optical properties of a metamaterial consisting of thin layers of alternating metal and dielectric. We can model this material as a homogeneous effective medium with

Using the Green-function approach to the problem of quantization of the phenomenological Maxwell theory, the propagation of quantized radiation through dispersive and absorptive multilayer dielectric plates is studied and it is shown that inclusion in the calculations of losses in the photonic band gaps may substantially change the barrier traversal times.

Removal of absorption and increase in resolution in a near-field lens via optical gain
A recent paper [J. B. Pendry, Phys. Rev. Lett. 85, 3966 (2000)] showed how to construct a superlens that focuses the near-field radiation and, hence, produce an image resolution unlimited by
