Heating the surface of the structure under test for a short period of time generates a non-stationary temperature distribution and thus a thermal contrast between the defect and the sound material. Due to measurement noise, preprocessing of the experimental data is necessary, before reconstruction algorithms can be applied. We propose a decomposition of the measured temperature into Green's function solutions to eliminate noise.}, language = {en} } @inproceedings{PetracekMaesBurgeretal.2012, author = {Petracek, Jiri and Maes, Bjorn and Burger, Sven and Luksch, Jaroslav and Kwiecien, Pavel and Richter, Ivan}, title = {Simulation of high-Q nanocavities with 1D photonic gap}, booktitle = {Transparent Optical Networks (ICTON)}, publisher = {IEEE}, doi = {10.1109/ICTON.2012.6253762}, pages = {1 -- 4}, year = {2012}, language = {en} } @inproceedings{PetracekLukschMaesetal.2012, author = {Petracek, Jiri and Luksch, Jaroslav and Maes, Bjorn and Burger, Sven and Kwiecien, Pavel and Richter, Ivan}, title = {Simulation of photonic crystal nanocavities using a bidirectional eigenmode propagation algorithm: a comparative study}, booktitle = {Micro- and nanophotonic materials and devices}, editor = {Ferrari, M. and Marciniak, M. and Righini, G. and Szoplik, T. and Varas, S.}, publisher = {IFN-CNR, Trento, Italy}, isbn = {9788377980200}, pages = {109 -- 112}, year = {2012}, language = {en} } @article{SchlosserSchothBurgeretal.2011, author = {Schlosser, Felix and Schoth, Mario and Burger, Sven and Schmidt, Frank and Knorr, Andreas and Mukamel, S. and Richter, Marten}, title = {Ultrafast nonlinear spectroscopy with spatially confined fields}, volume = {1398}, journal = {AIP Conference Proceedings}, publisher = {AIP}, doi = {10.1063/1.3644223}, pages = {94 -- 96}, year = {2011}, language = {en} } @inproceedings{SchlosserSchothBurgeretal.2012, author = {Schlosser, Felix and Schoth, Mario and Burger, Sven and Schmidt, Frank and Knorr, Andreas and Mukamel, Shaul and Richter, Marten}, title = {Coherent Nonlinear Spectroscopy with Spatiotemporally Controlled Fields}, booktitle = {CLEO/QELS}, publisher = {Optical Society of America}, doi = {10.1364/QELS.2012.QF3D.6}, pages = {QF3D.6}, year = {2012}, language = {en} } @inproceedings{SchlosserSchothHiremathetal.2012, author = {Schlosser, Felix and Schoth, Mario and Hiremath, Kirankumar and Burger, Sven and Schmidt, Frank and Knorr, Andreas and Mukamel, Shaul and Richter, Marten}, title = {Combining nanooptical fields and coherent spectroscopy on systems with delocalized excitons}, volume = {8260}, booktitle = {Proc.
