This study uses a laser patterning setup to write defect structures into conjugated polymer microcavity. We show that the enhances optical confinement and reduces lasing threshold.

The interaction between semiconductor materials and electromagnetic fields resonating in microcavities or the light–matter coupling is of both fundamental practical significance for improving performance various photonic technologies. demonstration effects emerging perovskite-based optoelectronic devices via optical pumping electrical readout (e.g., photovoltaics) vice versa light-emitting diod...

We study theoretically optomechanical interactions in a semiconductor microcavity with embedded quantum well under the optical pumping by Bessel beam, carrying non-zero orbital momentum. Due to transfer of momentum from light phonons, can act as an acoustic circulator: it rotates propagation direction incident phonon certain angle clockwise or anticlockwise. heating and cooling effects, circula...

We investigate experimentally one of the main features of a quantum fluid constituted by exciton polaritons in a semiconductor microcavity, that is, quantum degeneracy of a macroscopic fraction of the particles. We show that resonant pumping allows us to create a macroscopic population of polaritons in one quantum state. Furthermore, we demonstrate that parametric polariton scattering results i...

The authors introduce new measures of directional emission in microcavity lasers by exploiting the notion Shannon entropy, and suggest that an entropic measure unidirectional is more accurate efficient than former measures.

We present the results of z-scan studies carried out on photonic crystals and microcavities made of Bi:YIG, showing the enhancement of light self-action in the vicinity of the microcavity mode and the wavelength-dependent intensity localization in certain type layers at the longwavelength edge of the photonic bandgap.

A design of microfluidic devices is presented to integrate single-mode, liquid-core waveguides with microfluidic channels that generate and deliver disklike emulsion microdroplet cavities doped with an organic dye. The microcavity modes can be directly coupled to the liquid waveguide. Cavity-enhanced spontaneous emission was observed at the waveguide with low pump pulse energy.

We present a generic model for the description of non-equilibrium Bose-Einstein condensates, suited for the modelling of non-resonantly pumped polariton condensates in a semiconductor microcavity. The excitation spectrum and scattering of the non-equilibrium condensate with a defect are discussed.

We show that the combined effect of photon emission and Coulomb interactions may drive an exciton-polariton system towards a dynamical coherent state, even without phonon thermalization or any other relaxation mechanism. Exact diagonalization results for a finite system (a multilevel quantum dot interacting with the lowest-energy photon mode of a microcavity) are presented in support of this st...
