“…These 3D photonic crystals strongly interact with light. 16,17 Extensive details on the fabrication and characterization of the inverse opals are reported in Ref. We use CdSe-ZnSe ͑core-shell͒ colloidal quantum dots ͑QDs͒ as light sources because of their high fluorescence quantum efficiency and narrow homogeneous spectral width.…”

We observe experimentally that ensembles of quantum dots in three-dimensional (3D) photonic crystals reveal strongly nonexponential time-resolved emission. These complex emission decay curves are analyzed with a continuous distribution of decay rates. The log-normal distribution describes the decays well for all studied lattice parameters. The distribution width is identified with variations of the radiative emission rates of quantum dots with various positions and dipole orientations in the unit cell. We find a striking sixfold change of the width of the distribution by varying the lattice parameter. This interpretation qualitatively agrees with the calculations of the 3D projected local density of states. We therefore conclude that fluorescence decay of ensembles of quantum dots is highly nonexponential to an extent that is controlled by photonic crystals.

“…Photonic crystals, for example, can modify the radiative density of states associated with nearby electromagnetic sources. Optical effects such as superradiance [1], enhanced or inhibited spontaneous emission [2], ultrarefraction [3] and even negative refraction [4,5] have been predicted for various photonic lattice configurations.…”

Electromagnetic Wave Propagation in Media with Indefinite Permittivity and Permeability Tensors

We study the behavior of wave propagation in materials for which not all of the principle elements of the permeability and permittivity tensors have the same sign. We find that a wide variety of effects can be realized in such media, including negative refraction, near-field focusing and high impedance surface reflection. In particular a bi-layer of these materials can transfer a field distribution from one side to the other, including near-fields, without requiring internal exponentially growing waves.

“…So SPPs can be used to control the radiation rate of the excitation and improve the quantum yield. In this respect, several theoretical and experimental realizations have been studied, such as emitters close to interface [11,12], nanospheres [13], nano-rings [14], inside cavities [15,16], and photonic crystals [17][18][19].…”

Abstract-We study the characteristics of nano-optical antenna made of two gold nano-particles by three dimensional numerical calculations in visible and near infrared bands. To carry the computational burden and guarantee the precision and speed of a three dimensional FDTD calculation, adaptive mesh refinement technology is used. In this paper, we first highlight the concrete way of controlling the emitter position and orientation to fulfill the requirements of larger spontaneous emission enhancement. Then, we analyze the far field distribution and find that the far field directivity is strongly influenced by surface plasmon polaritons (SPPs). Choosing the incident wavelength of 600 nm, we compute the decay rates and radiant efficiency as a function of antenna geometry limitations. Next, the particle aspect ratio is optimized, and we obtain that L/R = 4 is the best for our optical-antenna. Furthermore, we present a spectrum analysis. Around 5000 fold spontaneous emission enhancement is successfully achieved. Finally, we find a piecewise linearity relationship between the particle length and resonant wavelength.
