They are used in a wide range of fields, from communications, recording, and authentication, to display, medical diagnostics, and clean energy. The light employed in these applications consists not only of visible light, but also includes wavelengths ranging from infrared, ultraviolet, and X-rays, to gamma rays. It may be said that optical devices are made up of the interaction between the electrons (or atomic nuclei) in these electromagnetic waves and in matter. Regardless of the wavelength domain, fundamental physics, which forms the basis of quantum mechanics, plays an important role in the interaction between light and matter. In this research, we capture optical devices from the perspective of the interaction between light and matter, and aim to discover new phenomena and their applications on those new devices even as we carry out basic research. In particular, in the six areas of semiconductor devices, liquid crystal elements, strongly-correlated electron system optical devices, positron emission tomography (PET), organic optical devices, and ultrashort pulse optical devices in the attosecond domain, it is our goal to achieve new and material results through this joint research by harnessing the knowledge of all the researchers involved.<\/p>\n<p>The physics relating to these optical devices are also intrinsically challenging themes in fundamental physics. These include electron-hole pair production process using light, changes in electron conditions in the interface, the interaction between electron spin and orbital angular momentum, spin relaxation through the interaction of electron spin and nuclear spin, phase transition phenomenon arising from liquid crystals, tunnel effect of electrons, collective motion arising from interaction between the electrons, non-equilibrium avalanche phenomenon in high electric fields, etc. In order to throw light on these areas of fundamental physics, we aim to uncover new phenomena based on these ideas, and apply them to devices.<\/p>\n<h3>Researchers<\/h3>\n<p>Yuka TABE (Professor, Faculty of Science and Engineering)<br \/>\nAtsushi TACKEUCHI (Professor, Faculty of Science and Engineering)<br \/>\nTakuro KATSUFUJI (Professor, Faculty of Science and Engineering)<br \/>\nJun KATAOKA (Associate professor, Faculty of Science and Engineering)<br \/>\nTaishi TAKENOBU (Professor, Faculty of Science and Engineering)<br \/>\nHiromichi NIIKURA (Associate professor, Faculty of Science and Engineering)<br \/>\nTakao AOKI (Associate professor, Faculty of Science and Engineering)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Concluded Laboratory 2015\/03\/31 Director : Yuka TABE Professor,Faculty of Science and Engineering Research the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[97],"tags":[],"class_list":["post-375","post","type-post","status-publish","format-standard","hentry","category-other-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/posts\/375","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/comments?post=375"}],"version-history":[{"count":1,"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/posts\/375\/revisions"}],"predecessor-version":[{"id":376,"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/posts\/375\/revisions\/376"}],"wp:attachment":[{"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/media?parent=375"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/categories?post=375"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/ori\/wp-json\/wp\/v2\/tags?post=375"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
