More specifically, he will talk about currently on-going research using integrated subwavelength patterned metal nanoantennas on various detector materials for infrared detection: midwave infrared indium gallium arsenide antimonide detectors, longwave infrared graphene detectors, and shortwave infrared germanium detectors. These subwavelength structures, or nanoantennas, offer a means to make infrared detectors much thinner, thus lowering the dark current and improving performance.\u0026nbsp; The nanoantenna converts incoming plane waves to more tightly bound and concentrated surface waves (similar to surface plasmons).\u0026nbsp; The active material only needs to extend as far as these bound fields.\u0026nbsp; In the case of graphene detectors, which are only one or two atomic layers thick, such field concentration is a necessity for usable device performance, as single pass absorption is insufficient. Nanoantenna integration and fabrication vary considerably across these platforms as do the considerations taken into account during design.\u0026nbsp; Here he will discuss the motivation for these devices and show examples for the three material systems.\u0026nbsp; Characterization results are included for the midwave infrared detector.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio: \u003C\/strong\u003EDavid Peters is currently a Principal Member of Technical Staff at Sandia National Laboratories in the Applied Photonic Microsystems organization.\u0026nbsp; He received his PhD in Electrical Engineering from the Georgia Institute of Technology in 2001.\u0026nbsp; From 2001 to 2004 he was a Director of Central Intelligence Post-Doc at Sandia investigating 2D and 3D photonic crystals.\u0026nbsp; His current interests include the theory, design, and modeling of diffractive optics, plasmonic devices, metamaterials, and photonic crystals with a focus on midwave and thermal infrared applications.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"A guest lecture with David Peters, Principal Member of Technical Staff at Sandia National Laboratories in the Applied Photonic Microsystems organization."}],"uid":"27863","created_gmt":"2014-02-27 09:20:57","changed_gmt":"2017-04-13 21:23:04","author":"Christa Ernst","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2014-03-05T17:30:00-05:00","event_time_end":"2014-03-05T19:00:00-05:00","event_time_end_last":"2014-03-05T19:00:00-05:00","gmt_time_start":"2014-03-05 22:30:00","gmt_time_end":"2014-03-06 00:00:00","gmt_time_end_last":"2014-03-06 00:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"279371":{"id":"279371","type":"image","title":"David Peters Sandia Labs","body":null,"created":"1449244168","gmt_created":"2015-12-04 15:49:28","changed":"1475894971","gmt_changed":"2016-10-08 02:49:31","alt":"David Peters Sandia Labs","file":{"fid":"198872","name":"d._peters.jpg","image_path":"\/sites\/default\/files\/images\/d._peters_0.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/d._peters_0.jpg","mime":"image\/jpeg","size":24412,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/d._peters_0.jpg?itok=895gd2tJ"}},"279381":{"id":"279381","type":"image","title":"D.
