One of the fundamental works concerning field singularities has been proposed in 1972 [1] and states that the electromagnetic energy density must be integrable over any finite\r\ndomain, even if this domain contains singularities. It is shown, that the magnetic field \u0002H(\u0003, ϕ) and electric field \u0002E(\u0003, ϕ) are proportional to ∝ \u0003(t−1) for \u0003 → 0. The variable \u0003 is the distance to the edge and t has to fulfill the integrability condition and thus is restricted to 0 < t < 1. This result is often used to reduce the error corresponding to the singularity without increasing the numerical effort [2 - 5]. For this purpose, a correction factor K is estimated by inserting the proportionality into the wave equation. It is shown, that this method improves the accuracy of the result significantly, however the order of convergence is often not studied. In [4] a method to modify the material parameters in order to use analytic results to improve the numeric calculation is presented. In this contribution we will - inspired by the scheme given in [4] - develop a new method to estimate a correction factor for perfect conducting materials (PEC) and demonstrate the improvement of the results compared to the standard edge correction. Therefore analytic results (comparable to [1]) are consequently merged with the scheme in [4]. The main goal of this work is the calculation of the second harmonic generation (SHG) in the wave response of so-called metamaterials [6]. Frequently these structures\r\ncontain sharp metallic edges with field singularities at the interfaces which have a strong impact on the SHG signals. Thus, an accurate simulation of singularities is highly important. However, the following approach can also be applied to many other setups, and one of them is shown in the example below.","lang":"eng"}],"file":[{"file_size":209412,"access_level":"open_access","file_name":"2010 Classen,Förstner, Meier T,Schuhmann_Enhanced FDTD edge correction for nonlinear effects calculation.pdf","date_updated":"2018-09-04T19:31:42Z","relation":"main_file","content_type":"application/pdf","file_id":"4168","creator":"hclaudia","date_created":"2018-08-28T08:36:44Z"}],"date_created":"2018-08-28T08:34:52Z","keyword":["tet_topic_numerics"],"type":"conference","department":[{"_id":"61"},{"_id":"15"},{"_id":"293"},{"_id":"170"},{"_id":"230"},{"_id":"35"},{"_id":"34"}]},{"publisher":"The Optical Society","_id":"4172","urn":"41725","user_id":"16199","ddc":["530"],"volume":18,"status":"public","has_accepted_license":"1","oa":"1","file_date_updated":"2018-09-04T20:02:01Z","citation":{"ama":"Piegdon KA, Declair S, Förstner J, et al.

The quantum dots serve as emitters feeding the optical modes of the photonic cavity. By changing temperature, the liquid crystal undergoes a phase transition from the isotropic to the nematic state, which can be used\r\nas an effective tuning mechanism of the photonic modes of the cavity. In the nematic state, the uniaxial electrical anisotropy of the liquid crystal molecules can be exploited for orienting the material in an electric field,\r\nthus externally controlling the birefringence of the material. Using this effect, an electric field induced tuning of the modes is achieved. Numerical simulations using the finite-differences time-domain (FDTD) technique\r\nemploying an anisotropic dielectric medium allow to understand the alignment of the liquid crystal molecules on the surface of the microdisk resonator.","lang":"eng"}]},{"publication":"Advances in Optical Sciences Congress","abstract":[{"lang":"eng","text":"We experimentally and theoretically investigate microdisk resonators with embedded quantum dots immersed in a liquid crystal in its nematic phase, showing the tunabililty of the photonic modes via external parameters like temperature or electric field."}],"date_created":"2018-08-28T09:28:38Z","department":[{"_id":"15"},{"_id":"287"},{"_id":"293"},{"_id":"230"},{"_id":"35"},{"_id":"313"},{"_id":"170"},{"_id":"35"},{"_id":"34"},{"_id":"61"}],"keyword":["tet_topic_microdisk"],"type":"conference","author":[{"id":"158","full_name":"Förstner, Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","first_name":"Jens"},{"first_name":"Cedrik","orcid":"https://orcid.org/0000-0002-3787-3572","last_name":"Meier","full_name":"Meier, Cedrik","id":"20798"},{"full_name":"Piegdon, Karoline","last_name":"Piegdon","first_name":"Karoline"},{"first_name":"Stefan","last_name":"Declair","full_name":"Declair, Stefan"},{"full_name":"Hoischen, Andreas","first_name":"Andreas","last_name":"Hoischen"},{"full_name":"Urbanski, Mark","first_name":"Mark","last_name":"Urbanski"},{"id":"344","orcid":"0000-0001-8864-2072","last_name":"Meier","first_name":"Torsten","full_name":"Meier, Torsten"},{"last_name":"Kitzerow","first_name":"Heinz-Siegfried","full_name":"Kitzerow, Heinz-Siegfried","id":"254"}],"publication_identifier":{"isbn":["9781557528735"]},"year":"2009","title":"Coupling Dynamics of Quantum Dots in a Liquid-Crystal-Tunable Microdisk Resonator","publication_status":"published","date_updated":"2025-12-16T16:41:31Z","language":[{"iso":"eng"}],"article_number":"paper NTuC2","doi":"10.1364/nlo.2009.ntuc2","citation":{"bibtex":"@inproceedings{Förstner_Meier_Piegdon_Declair_Hoischen_Urbanski_Meier_Kitzerow_2009, title={Coupling Dynamics of Quantum Dots in a Liquid-Crystal-Tunable Microdisk Resonator}, DOI={<a href=\"https://doi.org/10.1364/nlo.2009.ntuc2\">10.1364/nlo.2009.ntuc2</a>}, number={paper NTuC2}, booktitle={Advances in Optical Sciences Congress}, publisher={OSA Technical Digest (CD) (Optical Society of America, 2009), paper NTuC2}, author={Förstner, Jens and Meier, Cedrik and Piegdon, Karoline and Declair, Stefan and Hoischen, Andreas and Urbanski, Mark and Meier, Torsten and Kitzerow, Heinz-Siegfried}, year={2009} }","ama":"Förstner J, Meier C, Piegdon K, et al.
