“…It is well-known that the effective medium theory applied for characterization of dielectric multilayer system and HMMs can experience a breakdown, depending on the thickness of each layer, number of periods, etc. 53,81 . Recently the optimum number of periods of a multilayer HMM for the enhancement of PL from a quantum emitter was theoretically analyzed 82 .…”

“…The Purcell factor was demonstrated to grow almost linearly with the number of periods in contrary to ref. 75,81 . It means that it is necessary to take into account properties of active material since it has significant influence on spontaneous emission process.…”

“…The very first experimental verification of stimulated emission of surface plasmons propagating on top of metal-dielectric multilayered HMMs coated with optically pumped dye-doped polymer for the wavelengths around 860 nm, as well as loss compensation was reported in ref. 81 . The HMMs were composed of Ag/MgF 2 alternating layers.…”

Photoluminescence including fluorescence plays a great role in a wide variety of applications from biomedical sensing and imaging to optoelectronics. Therefore, the enhancement and control of photoluminescence has immense impact on both fundamental scientific research and aforementioned applications. Among various nanophotonic schemes and nanostructures to enhance the photoluminescence, we focus on a certain type of nanostructures, hyperbolic metamaterials (HMMs). HMMs are highly anisotropic metamaterials, which produce intense localized electric fields. Therefore, HMMs naturally boost photoluminescence from dye molecules, quantum dots, nitrogen-vacancy centers in diamonds, perovskites and transition metal dichalcogenides. We provide an overview of various configurations of HMMs, including metal-dielectric multilayers, trenches, metallic nanowires, and cavity structures fabricated with the use of noble metals, transparent conductive oxides, and refractory metals as plasmonic elements. We also discuss lasing action realized with HMMs.

“…By analyzing the Purcell factor (Figure 4b), it is clear that the Au top layer provided a higher value of the Purcell factor with respect to the Al2Ox top layer over the entire wavelength range considered. This behavior is due to the coupling of the dipole with plasmonic waves sustained by the thin layer of gold [16][17][18], First, we considered the configuration with the Au top layer. The analysis revealed a propagating mode well beyond the glass line (Figure 3a).…”

Funneling Spontaneous Emission into Waveguides via Epsilon-Near-Zero Metamaterials

In this work, we discuss the use of epsilon-near-zero (ENZ) metamaterials to efficiently couple light radiated by a dipolar source to an in-plane waveguide. We exploit both enhanced and directional emission provided by ENZ metamaterials to optimize the injection of light into the waveguide by tuning the metal fill factor. We show that a net increase in intensity injected into the waveguide with respect to the total power radiated by the isolated dipole can be achieved in experimentally feasible conditions. We think the proposed system may open up new opportunities for several optical applications and integrated technologies, especially for those limited by outcoupling efficiency and emission rate.

Hyperbolic metamaterials are a family of nanophotonic architectures allowing for the unique control of photonic local density of states. Such a property makes metamaterials prospective to use them with light-emitting objects or to apply as meta-electrodes for optoelectronic devices, where the control of recombination properties plays a decisive role. On the other hand, layered quasi-2D halide perovskites (Ruddlesden–Popper phase) attract high attention due to their low cost, broadband spectral tunability, and outstanding optoelectronic properties. Here, we show how to accelerate photoluminescence with smart engineering of photonic density of states (i.e., via the Purcell effect) by depositing a perovskite film on a hyperbolic metamaterial. We experimentally confirm acceleration of radiative recombination by almost 3 times. This effect can be useful in light-emitting devices, where interplay between radiative and non-radiative channels of charge carrier recombination is crucial.
