Wave-mixing experiments are often described with semiclassical models, where the light is modeled classically and the material quantum mechanically. Here, however, we use a fully quantized model, where the light is given by a quantum state of light. Quantum light involves more degrees of freedom than classical light as e.g., its photon statistics and quantum correlations, which is a promising resource for quantum devices, such as quantum memories. The light-matter interaction is treated with a Jaynes-Cummings type model and the quantum field is given by a single mode since the quantum dots are embedded in a microcavity. We present numerical simulations of the four-wave-mixing response of a homogeneous system for pulse sequences and find a significant dependence of the result on the photon statistics of the incident pulses. The model constitutes a problem with a large state space which arises from the frequency distribution of the transition energies of the inhomogeneously broadened quantum dot ensemble that is coupled with a quantum light mode. Here we approximate the dynamics by summing over individual quantum dot-microcavity systems. Photon echoes arising from the excitation with different quantum states of light are simulated and compared."}],"language":[{"iso":"eng"}]},{"issue":"12","publication_status":"published","publication_identifier":{"issn":["1094-4087"]},"citation":{"ieee":"X.

The situation is, however, different in solid-state systems as it has been demonstrated that due to collisions with neighboring atomic cores of the crystal lattice strong HHG can be generated even by elliptically- and circularly-polarized laser fields. Here we apply PG to solid-state systems and find that the conventional PG technique is inefficient for the generation of isolated ultrashort harmonic pulse bursts. In contrast, we demonstrate that a polarization-skewed laser pulse is able to confine the harmonic emission to a time window of less than one-tenth of the laser cycle.

PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation.","lang":"eng"}],"language":[{"iso":"eng"}],"ddc":["530"],"keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"issue":"1","quality_controlled":"1","year":"2023","date_created":"2023-07-06T06:34:37Z","publisher":"Springer Science and Business Media LLC","title":"Dynamic control of hybrid grafted perfect vector vortex beams","type":"journal_article","status":"public","user_id":"30525","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"_id":"45868","file_date_updated":"2023-07-06T06:40:28Z","article_number":"3915","publication_status":"published","publication_identifier":{"issn":["2041-1723"]},"has_accepted_license":"1","citation":{"apa":"Ahmed, H., Ansari, M.

It is advantageous to operate the systems at telecommunication wavelengths and to integrate the setups for these applications in order to improve stability, compactness and scalability. A new promising material platform for integrated quantum optics is lithium niobate on insulator (LNOI). Here, we realise Hong-Ou-Mandel (HOM) interference between telecom photons from an engineered parametric down-conversion source in an LNOI directional coupler. The coupler has been designed and fabricated in house and provides close to perfect balanced beam splitting. We obtain a raw HOM visibility of (93.5 ± 0.7) %, limited mainly by the source performance and in good agreement with off-chip measurements.

The Ga droplets can be crystallized into GaAs quantum dots using a crystallization step under As flux. In order to model the complex process, including the masked deposition of the droplets and a reduction of their number during a thermal annealing step, a multiscale kinetic Monte Carlo (mkMC) simulation of self-assembled Ga droplet formation on AlGaAs is expanded for area-selective deposition. The simulation has only two free model parameters: the activation energy for surface diffusion and the activation energy for thermal escape of adatoms from a droplet. Simulated droplet numbers within the opening of the aperture agree quantitatively with the experimental results down to the perfect site-control, with one droplet per aperture. However, the model parameters are different compared to those of the self-assembled droplet growth. We attribute this to the presence of the mask in close proximity to the surface, which modifies the local process temperature and the As background. This approach also explains the dependence of the model parameters on the size of the aperture.</jats:p>"}],"status":"public","_id":"46278","department":[{"_id":"15"},{"_id":"230"}],"user_id":"42514","keyword":["General Materials Science","General Chemical Engineering"],"article_number":"466","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2079-4991"]},"publication_status":"published","issue":"3","year":"2023","intvolume":"        13","citation":{"ieee":"S.

In this work, we find that in a liquid crystal (LC) microcavity\nfilled with perovskite microplates, the pronounced TE-TM splitting gives rise\nto a strong SOC that leads to the spatial instability of microcavity polariton\ncondensates under single-shot excitation. Spatially varying hole burning and\nmode competition occurs between polarization components leading to different\ncondensate profiles from shot to shot. The single-shot polariton condensates\nbecome stable when the SOC vanishes as the TE and TM modes are spectrally well\nseparated from each other, which can be achieved by application of an electric\nfield to our LC microcavity with electrically tunable anisotropy. Our findings\nare well reproduced and traced back to their physical origin by our detailed\nnumerical simulations.
