As\r\ncounterpart to conventional radio antennas, they are able to increase optical felds in sub-wavelength volumes,\r\nto enhance excitation and emission of quantum emitters or to direct light, radiated by quantum emitters. The\r\ndirected emission of these antennas has been mainly pursued by surface plasmon based devices, e.g. Yagi-Uda\r\nlike antennas, which are rather complicated due to the coupling of several metallic particles. Also, like all metallic\r\nstructures in optical or infrared regime, these devices are very sensitive to fabrication tolerances and are affected\r\nby strong losses. It has been shown recently, that such directed emission can be accomplished by dielectric\r\nmaterials as well.\r\nIn this paper we present an optimization of nanoscopic antennas in the near infrared regime starting from a\r\nmetallic Yagi-Uda structure. The optimization is done via a particle-swarm algorithm, using full time domain\r\nfinite integration simulations to obtain the characteristics of the investigated structure, also taking into account\r\nsubstrates. Furthermore we present a dielectric antenna, which performs even better, due to the lack of losses\r\nby an appropriate choice of the dielectric material. These antennas are robust concerning fabrication tolerances\r\nand can be realized with different materials for both the antenna and the substrate, without using high index\r\nmaterials."}],"title":"Engineering plasmonic and dielectric directional nanoantennas","author":[{"first_name":"Andre","full_name":"Hildebrandt, Andre","last_name":"Hildebrandt"},{"id":"138","first_name":"Matthias","full_name":"Reichelt, Matthias","last_name":"Reichelt"},{"orcid":"0000-0001-8864-2072","last_name":"Meier","full_name":"Meier, Torsten","first_name":"Torsten","id":"344"},{"orcid":"0000-0001-7059-9862","first_name":"Jens","id":"158","last_name":"Förstner","full_name":"Förstner, Jens"}],"publication_status":"published","date_created":"2018-08-20T10:04:52Z","doi":"10.1117/12.2036588","file_date_updated":"2018-08-20T10:10:25Z","department":[{"_id":"61"},{"_id":"15"},{"_id":"293"},{"_id":"230"},{"_id":"170"}],"volume":8984,"has_accepted_license":"1","language":[{"iso":"eng"}],"page":"89841G-8941G-6","publication":"Ultrafast Phenomena and Nanophotonics XVIII","editor":[{"last_name":"Betz","full_name":"Betz, Markus","first_name":"Markus"},{"first_name":"Abdulhakem Y.","last_name":"Elezzabi","full_name":"Elezzabi, Abdulhakem Y."},{"first_name":"Jin-Joo","last_name":"Song","full_name":"Song, Jin-Joo"},{"full_name":"Tsen, Kong-Thon","last_name":"Tsen","first_name":"Kong-Thon"}],"user_id":"49063","year":"2014","status":"public","_id":"3939","type":"conference","keyword":["tet_topic_opticalantenna"],"publisher":"SPIE","ddc":["530"],"citation":{"short":"A.
