WS2 possesses valley excitons that selectively couple with one-handed circularly polarized light. At the same time, the chiral plasmonic metasurface exhibits spin-momentum locking, leading to a robust polarization response in the far field. Using a scattering formalism based on the coupled mode method, we analyze various optical properties of the WS2 monolayer. Specifically, we demonstrate the generation of circular dichroism in the transition metal dichalcogenide (TMD) by harnessing the excitation of surface plasmon polaritons (SPPs) in the metasurface. Moreover, we observe the emergence of other guided modes, opening up exciting possibilities for further exploration in TMD-based devices. 000130559 536__ $$9info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2020-115221GB-C41 000130559 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000130559 590__ $$a2.8$$b2023 000130559 592__ $$a0.662$$b2023 000130559 591__ $$aOPTICS$$b43 / 119 = 0.361$$c2023$$dQ2$$eT2 000130559 593__ $$aElectronic, Optical and Magnetic Materials$$c2023$$dQ2 000130559 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b230 / 439 = 0.524$$c2023$$dQ3$$eT2 000130559 594__ $$a5.5$$b2023 000130559 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000130559 700__ $$aGenet, Cyriaque 000130559 700__ $$0(orcid)0000-0001-9273-8165$$aMartín-Moreno, Luís 000130559 773__ $$g13, 11 (2023), 3366 [10 pp.]$$pOPTICAL MATERIALS EXPRESS$$tOPTICAL MATERIALS EXPRESS$$x2159-3930 000130559 8564_ $$s11920450$$uhttps://zaguan.unizar.es/record/130559/files/texto_completo.pdf$$yVersión publicada 000130559 8564_ $$s2385729$$uhttps://zaguan.unizar.es/record/130559/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000130559 909CO $$ooai:zaguan.unizar.es:130559$$particulos$$pdriver 000130559 951__ $$a2024-11-22-12:10:23 000130559 980__ $$aARTICLE
