A commonly used approach to describe theoretical properties includes a phenomenological single-mode equation that complements the equation for the nonlinear optical response (interband polarization) of the semiconductor. Here, we show how to replace the single-mode equation by a fully predictive transfer function method that, in contrast to the single-mode equation, accounts for propagation, retardation, and pulse-filtering effects of the incident light field traversing the distributed Bragg reflector (DBR) mirrors, without substantially increasing the numerical complexity of the solution. As examples, we use cavities containing GaAs quantum wells and transition-metal dichalcogenides (TMDs).</jats:p>"}],"publication":"Applied Optics","doi":"10.1364/ao.392014","date_updated":"2023-04-20T15:42:52Z","author":[{"first_name":"M.","last_name":"Carcamo","full_name":"Carcamo, M."},{"full_name":"Schumacher, Stefan","id":"27271","last_name":"Schumacher","orcid":"0000-0003-4042-4951","first_name":"Stefan"},{"full_name":"Binder, R.","last_name":"Binder","first_name":"R."}],"volume":59,"citation":{"chicago":"Carcamo, M., Stefan Schumacher, and R.

With their additional degree of freedom, the vorticity, they have been widely investigated in many physical systems and different materials for fundamental interest and for applications in data storage and information processing. Vortices have also been observed in non-equilibrium exciton-polariton condensates in planar semiconductor microcavities. There they appear spontaneously or can be created and pinned in space using ring-shaped optical excitation profiles. However, using the vortex state for information processing not only requires creation of a vortex but also efficient control over the vortex after its creation. Here we demonstrate a simple approach to control and switch a localized polariton vortex between opposite states. In our scheme, both the optical control of vorticity and its detection through the orbital angular momentum of the emitted light are implemented in a robust and practical manner.","lang":"eng"}],"publication":"Nature communications","main_file_link":[{"url":"https://www.nature.com/articles/s41467-020-14702-5","open_access":"1"}],"doi":"10.1038/s41467-020-14702-5","oa":"1","date_updated":"2023-04-21T11:23:46Z","author":[{"first_name":"Torsten","id":"344","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier"},{"full_name":"Ma, Xuekai","last_name":"Ma","first_name":"Xuekai"},{"last_name":"Berger","full_name":"Berger, Bernd","first_name":"Bernd"},{"first_name":"Marc","full_name":"Aßmann, Marc","last_name":"Aßmann"},{"last_name":"Driben","full_name":"Driben, Rodislav","first_name":"Rodislav"},{"last_name":"Schneider","full_name":"Schneider, Christian","first_name":"Christian"},{"first_name":"Sven","full_name":"Höfling, Sven","last_name":"Höfling"},{"first_name":"Stefan","id":"27271","full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher"}],"volume":11,"citation":{"apa":"Meier, T., Ma, X., Berger, B., Aßmann, M., Driben, R., Schneider, C., Höfling, S., &#38; Schumacher, S.

An aspect of particular interest is the active\r\ncontrol of such patterns. In nonlinear optical systems this can be used for\r\nall-optical switching with transistor-like performance, for example realized\r\nwith polaritons in a planar quantum-well semiconductor microcavity. Here we\r\nfocus on a specific configuration which takes advantage of the intricate\r\npolarization dependencies in the interacting optically driven polariton system.\r\nBesides detailed numerical simulations of the coupled light-field exciton\r\ndynamics, in the present paper we focus on the derivation of a simplified\r\npopulation competition model giving detailed insight into the underlying\r\nmechanisms from a nonlinear dynamical systems perspective. We show that such a\r\nmodel takes the form of a generalized Lotka-Volterra system for two competing\r\npopulations explicitly including a source term that enables external control.\r\nWe present a comprehensive analysis both of the existence and stability of\r\nstationary states in the parameter space spanned by spatial anisotropy and\r\nexternal control strength. We also construct phase boundaries in non-trivial\r\nregions and characterize emerging bifurcations. The population competition\r\nmodel reproduces all key features of the switching observed in full numerical\r\nsimulations of the rather complex semiconductor system and at the same time is\r\nsimple enough for a fully analytical understanding of the system dynamics.","lang":"eng"}],"publication":"arXiv:1903.12534","type":"preprint","language":[{"iso":"eng"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"230"},{"_id":"35"},{"_id":"27"}],"user_id":"16199","_id":"13340","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}]},{"type":"preprint","status":"public","abstract":[{"lang":"eng","text":"<jats:p>&lt;div&gt;\r\n\t\t\t&lt;div&gt;\r\n\t\t\t\t&lt;div&gt;\r\n\t\t\t\t\t&lt;p&gt;Molecular doping in conjugated polymers is a crucial process for their application in organic\r\nphotovoltaics and optoelectronics. In the present work we theoretically investigate p-type molecu-\r\nlar doping in a series of (poly[2,6-(4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b”]dithiophene)-alt-\r\n4,7-(2,1,3-benzothiadiazole)] (PCPDT-BT) conjugated oligomers with different lengths and three\r\nwidely-used dopants with different electron affinities, namely F4TCNQ, F6TCNNQ, and CN6-CP.\r\nWe study in detail the molecular geometry of possible oligomer-dopant complexes and its influence\r\non the doping mechanisms and electronic system properties. We find that the mechanisms of dop-\r\ning and charge transfer observed sensitively depend on the specific geometry of the oligomer-dopant\r\ncomplexes. For a given complex different geometries may exist, some of which show transfer of\r\nan entire electron from the oligomer chain onto the dopant molecule resulting in an integer-charge\r\ntransfer complex, leaving the system in a ground state with broken spin symmetry. In other ge-\r\nometries merely hybridization of oligomer and dopant frontier orbitals occurs with partial charge\r\ntransfer but spin-symmetric ground state. Considering the resulting electronic density of states both\r\ncases may well contribute to an increased electrical conductivity of corresponding film samples while\r\nthe underlying physical mechanisms are entirely different.\r\n&lt;/p&gt;\r\n\t\t\t\t&lt;/div&gt;\r\n\t\t\t&lt;/div&gt;\r\n\t\t&lt;/div&gt;</jats:p>"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"230"},{"_id":"35"},{"_id":"27"}],"user_id":"16199","_id":"13347","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"language":[{"iso":"eng"}],"publication_status":"published","citation":{"apa":"Dong, C.-D., &#38; Schumacher, S.
