We discuss the properties of a selection of cyanine dyes that form J-aggregates with narrow absorption bands, suitable for studying strong exciton-photon coupling in optical microcavities at room temperature. In particular, we show how the optical pr

The optical properties of microcavities (MCs) are strongly dependent on both polarization of incident and emitted light and its angle of observation. Here we report the measurements of cw- and time-resolved photoluminescence (PL) observed at negative

We have fabricated strongly coupled organic microcavities by laminating an organic thin film between two dielectric mirrors. The organic film consisted of J aggregates of a cyanine dye suspended in a transparent matrix. By applying a nonuniform force

We report the fabrication of high-finesse strongly coupled microcavities composed of a polystyrene film doped with the dye tetraphenyl-porphyrin zinc positioned between two high reflectivity dielectric mirrors. The bottom mirror was deposited by plas

In this study, we first report organic material based micropillar structures fabricated using advanced techniques based upon focused ion beam milling processes. Such a method provides a faster milling procedure as the beam of ions directly etches thr

A significant fraction of light generated within an organic light emitting diode (OLED) is often trapped within the structure within waveguide modes and is unable to escape usefully from the device. Addressing this issue is of significant importance,

We report on ultrafast dynamics of polaritons in organic microcavities. Polariton dynamics is found to be governed by fast vibronic relaxation and intersystem crossing. Lower polariton branch blue-shift indicates the presence of nonlinear interaction

Time and angle-resolved measurements reveal ultrafast dynamics of excitations in organic microcavities leading to dramatic modulation of probe transmission (~30%). We find that the induced changes have both fast and long-lived components. Fast respon

We demonstrate a two dimensional photonic crystal microcavity structure fabricated via focused ion beam (FIB) micro-machining techniques. The FIB, with the Ga ion beam directly rastered over a planar organic material, drilled small holes in a lattice

The cover depicts a micropillar microcavity containing a fluorescent organic dye, Lumogen Red, the fabrication of which is described on p. 742 by Lidzey and co-workers. The optical confinement resulting from the low-dimensionality of the pillar resul
