“…By coupling microcavities together with narrow channels, photonic molecules 7,8 and photonic crystal chains 9 have been created. In a chain the photonic band structure was shown to consist of bands in which light can propagate along the chain separated by gaps in which the propagation of light is inhibited.…”

“…During the last few years electronic quantum dots [24][25][26] as well as photonic quantum dots [27][28][29] have attracted considerable attention. In these microresonators the confined states of electronic or photonic quanizations are strong resonance states with a pronounced size dependence.…”

In this paper, new experimental results of the microwave spectral properties of quasistatic magnetoelectric (ME) particles based on small ferrite resonators with linear-form surface electrodes have been illustrated. Existence of local coupling between electric and magnetic dipolar polarizations, which can be essential for realization of the so-called bianisotropic materials, has been proved. Also, a method of boosting the ME effect in a particle has been suggested.

“…The square molecule is additionally invariant under rotations of 90 around this axis (C 4 symmetry). Figure 10 shows angle-integrated photoluminescence spectra of the linear and the square photonic molecules in comparison with the spectrum of a single photonic dot [21]. The dot size was 2.5 Â 2.5 mm, while the dimensions of the channels were 0.5 mm length and 2 mm width.…”

Scanning electron micrographs of photonic isomeres formed from four identical photonic dots arranged in different ways; a) shows a linear, b) a square and c) a T-shaped arrangement [21] cies can occur in the mode spectrum. For the square arrangement the higher symmetry as compared to the linear one leads to a twofold degeneracy of the molecule mode with middle energy.…”

A detailed control of light-matter interaction can be achieved by placing an optically active medium into a resonator. Here we want to demonstrate some aspects of such a control in semiconductors: In the first part of the article we will discuss the optical modes in microresonators with a three dimensional confinement of light (photonic dots) due to which the density of modes is dominated by sharp, discrete resonances. From optical spectroscopy insight into energies and field distributions of the modes is taken. More complicated confined photon geometries (photonic molecules) are obtained by connecting several photonic dots through narrow channels. The electromagnetic field distributions in these structures bear strong resemblences to bonding and anti-bonding orbitals in molecules. Also a model system of a photonic band gap structure can be created in this way: By increasing the number of coupled resonators in a linear chain the transition from an atomic-to a crystal-like system is obtained. The dependence of the band stucture on the geometry parameters as well as its modification by implementing defects have been studied in detail. In the second part we will then turn to the modification of light-matter interaction in photonic dots. Whereas for studying them, the optical modes were separated far from the electronic excitations, now the two excitations are brought in resonance. Both the regimes of weak and strong coupling are considered: In the strong coupling regime we observe the normal mode splitting of polaritons formed by a quantum well exciton and the several confined modes of photonic dots. The dependence of the Rabi splitting on the involved mode and on the resonator size is discussed. In the weak coupling regime we address the spontaneous emission of quantum dots that are embedded in photonic dots. Both an inhibition and a suppression of the emission could be demonstrated in resonators with a lateral metal coating.
