The cavities are evanescently excited under oblique angles by thin-film guided, in-plane unguided waves supported by one of the slab waveguides. Beyond a specific incidence angle, losses are fully suppressed. The interaction between the guided mode of the cavity-strip and the incoming slab modes leads to resonant behavior for specific incidence angles and gaps. For a single cavity, at resonance, the input power is equally split among each of the four output ports, while for two cavities an add-drop filter can be realized that, at resonance, routes the incoming power completely to the forward drop waveguide via the cavity. For both applications, the strength of the interaction is controlled by the gaps between cavities and waveguides.}}, author = {{Ebers, Lena and Hammer, Manfred and Berkemeier, Manuel B. and Menzel, Alexander and Förstner, Jens}}, issn = {{2578-7519}}, journal = {{OSA Continuum}}, keywords = {{tet_topic_waveguides}}, pages = {{3288}}, title = {{{Coupled microstrip-cavities under oblique incidence of semi-guided waves: a lossless integrated optical add-drop filter}}}, doi = {{10.1364/osac.2.003288}}, volume = {{2}}, year = {{2019}}, } @book{15265, editor = {{Linssen, Oliver and Mikusz, Martin and Volland, Alexander and Yigitbas, Enes and Engstler, Martin and Fazal-Baqaie, Masud and Kuhrmann, Marco}}, isbn = {{978-3-88579-692-3}}, title = {{{Projektmanagement und Vorgehensmodelle 2019.

Metalenses have emerged from the advance in the development of metasurfaces providing a new basis for recasting traditional lenses into thin, planar optical components capable of focusing light. The lens made of arrays of plasmonic gold nanorods were fabricated on a glass substrate by using electron beam lithography. A 1064 nm laser was used to create a high intensity circularly polarized light focal spot through metalens of focal length 800 µm, N.A. = 0.6 fabricated based on Pancharatnam-Berry phase principle. We demonstrated that optical rotation of birefringent nematic liquid crystal droplets trapped in the laser beam was possible through this metalens. The rotation of birefringent droplets convinced that the optical trap possesses strong enough angular momentum of light from radiation of each nanostructure acting like a local half waveplate and introducing an orientation-dependent phase to light. Here, we show the success in creating a miniaturized and robust metalens based optical tweezers system capable of rotating liquid crystals droplets to imitate an optical motor for future lab-on-a-chip applications.}}, author = {{Suwannasopon, Satayu and Meyer, Fabian and Schlickriede, Christian and Chaisakul, Papichaya and T-Thienprasert, Jiraroj and Limtrakul, Jumras and Zentgraf, Thomas and Chattham, Nattaporn}}, issn = {{2073-4352}}, journal = {{Crystals}}, number = {{10}}, pages = {{515}}, title = {{{Miniaturized Metalens Based Optical Tweezers on Liquid Crystal Droplets for Lab-on-a-Chip Optical Motors}}}, doi = {{10.3390/cryst9100515}}, volume = {{9}}, year = {{2019}}, } @article{13651, author = {{Chen, Shumei and Reineke, Bernhard and Li, Guixin and Zentgraf, Thomas and Zhang, Shuang}}, issn = {{1530-6984}}, journal = {{Nano Letters}}, number = {{9}}, pages = {{6278--6283}}, title = {{{Strong Nonlinear Optical Activity Induced by Lattice Surface Modes on Plasmonic Metasurface}}}, doi = {{10.1021/acs.nanolett.9b02417}}, volume = {{19}}, year = {{2019}}, }
