We investigate the cross interactions in a two-component polariton quantum fluid coherently driven by two independent pumping lasers tuned at different energies and momenta. We show that both the hysteresis cycles and the on-off threshold of one polariton signal can be entirely controlled by a second polariton fluid. Furthermore, we study the ultrafast switching dynamics of a driven polariton state, demonstrating the ability to control the polariton population with an external laser pulse, in less than a few picoseconds.

“…A lifting of the polarization degeneracy of the modes was already demonstrated for pillars with an elliptical cross section [35,[139][140][141][142] for GaAs-based MCs. For circularly shaped MCs with an unintended very small ellipticity this energy splitting increased with decreasing pillar diameter [143].…”

1 Introduction In the last years new ways to manipulate the light-matter interaction were found by modifying photonic components which confine light on the wavelength scale by means of semiconductor microcavities (MCs) [1]. The modified optical density of states produced by photonic structuring allows emission and absorption rates to be enhanced or suppressed. This is known as the Purcell effect which can be used to control the spontaneous emission [2]. Semiconductor MCs appear to a be highly attractive systems for the realization of a new generation of optoelectronic devices, polariton devices, optical switches and spin-memory elements. Several types of solid state MCs [1], including micropillars [3,4], microdisks [5,6] and photonic crystals [7,8], offer very small mode volumes V in combination with high quality factors Q. These factors describe the ability of the cavity to confine the light.

“…This may be achieved by altering the shape of the micropillars, leading to a control of the photonic mode structure to some extent [8]. With this technique a polarized QD emission could be shown for elliptically shaped MCs in the III-V material system [9,10]. Furthermore, the coupling of different QDs is of high interest for the generation of entangled photons which can be achieved via the electromagnetic field in a cavity [11] as well as by the coupling of several pillar MCs to increase the efficiency by the use of a photonic molecule (PM) [12].…”

A customization of the optical properties of pillar microcavities on the desired applications is essential for their future use as quantum‐optical devices. Therefore, all‐epitaxial cavities with CdSe or InGaN quantum dots embedded in pillar structures with different geometries have been realized by focused‐ion‐beam etching. The high temperature stability of the emission and the large oscillator strength of quantum dots made of these material systems are combined with small mode volume pillar microcavities to utilize the light‐matter interaction. The quality factors of circularly shaped pillar microcavities have been measured and compared to theoretical calculations. As a possibility to achieve polarized light emission, asymmetrically shaped microcavities are presented. Examples of an elliptically shaped pillar as well as of photonic molecules are investigated with respect to their photoluminescence characteristics and polarization.
