Through carrier recombination, the angular momentum of the spin-polarized carriers is transferred to photons, thus leading to the circularly polarized emitted light. The intuition for the operation of such spin-lasers can be obtained from simple bucket and harmonic oscillator models, elucidating their steady-state and dynamic response, respectively. These lasers extend the functionalities of spintronic devices and exceed the performance of conventional (spin-unpolarized) lasers, including an order of magnitude faster modulation frequency. Surprisingly, this ultrafast operation relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both viewed as detrimental in spintronics and conventional lasers. Spin-lasers provide a platform to test novel concepts in spin devices and offer progress connected to the advances in more traditional areas of spintronics."}],"_id":"59685","doi":"10.1016/j.ssc.2020.113949","language":[{"iso":"eng"}],"publication":"Solid State Communications","user_id":"15911","author":[{"last_name":"Žutić","full_name":"Žutić, Igor","first_name":"Igor"},{"first_name":"Gaofeng","full_name":"Xu, Gaofeng","last_name":"Xu"},{"full_name":"Lindemann, Markus","last_name":"Lindemann","first_name":"Markus"},{"first_name":"Paulo E.","full_name":"Faria Junior, Paulo E.","last_name":"Faria Junior"},{"last_name":"Lee","full_name":"Lee, Jeongsu","first_name":"Jeongsu"},{"first_name":"Velimir","last_name":"Labinac","full_name":"Labinac, Velimir"},{"last_name":"Stojšić","full_name":"Stojšić, Kristian","first_name":"Kristian"},{"first_name":"Guilherme M.","full_name":"Sipahi, Guilherme M.","last_name":"Sipahi"},{"first_name":"Martin R.","full_name":"Hofmann, Martin R.","last_name":"Hofmann"},{"id":"115298","full_name":"Gerhardt, Nils Christopher","last_name":"Gerhardt","first_name":"Nils Christopher","orcid":"0009-0002-5538-231X"}],"publication_identifier":{"issn":["0038-1098"]},"date_created":"2025-04-25T07:11:46Z","publisher":"Elsevier BV","title":"Spin-lasers: spintronics beyond magnetoresistance","publication_status":"published","citation":{"ieee":"I.
