We report on composite-cavity microresonators comprising a vertical cavity and a distributed feedback structure. First-order diffraction on the second-order Bragg grating serves as coupling mechanism between the two resonator elements. Employing the

By placing a thin silver grating inside a microcavity comprised of an organic semiconductor and two dielectric mirrors, researchers show that coherent emission can be selectively stimulated between in- and out-of-phase-locked arrays at room temperatu

A homogeneous microcavity is excited in two tightly focused spatially separated spots with a few μm distance. The radius of the generated cavity modes exceeds the excited regions such that the quasimodes of both spots overlap in space. Coherent coup

Highly conductive electrodes are a prerequisite for electrically pumped organic lasers. We investigate the influence of very thin metal contacts in an electrically active organic microcavity. We test different deposition techniques and seed layers to

We report on the dynamics of laser emission from an anisotropic organic microcavity filled with the guest-host composite of tris-(8-hydroxy quinoline) aluminium (Alq3) and 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM). In a s

By adding photonic wire structures to an organic microcavity, we create an additional confinement and a Bloch-like band structure in the dispersion of periodically structured cavities. We experimentally observe spontaneous and stimulated emission fro

The microstructural, optical and electrical properties of Si-, Ge- and Sn-implanted silicon dioxide layers were investigated. It was found, that these layers exhibit strong Photoluminescence (PL) around 2.7 eV (Si) and between 3 and 3.2 eV (Ge, Sn) a

The photoluminescence (PL) and electroluminescence (EL) properties of Ge-implanted SiO2 films thermally-grown on a Si substrate have been investigated and compared to those of Si-implanted SiO2 films. It is found that the blue-violet PL from both Si

We report on cross-coupled composite-cavity microresonators consisting of a vertical cavity and a second-order distributed feedback structure which employ the same organic active medium and support surface-normal and in-plane emission at the same tim
