Currently, this technology is dominated by silicon, but van der Waals (vdW) materials with a high refractive index can offer a very advanced alternative. Still, up to now, it was not clear if the optical anisotropy perpendicular to the layers might be a hindering factor for the development of vdW nanophotonics. Here, we studied WS2-based waveguides in terms of their optical properties and, particularly, in terms of possible crosstalk distance. Surprisingly, we discovered that the low refractive index in the direction perpendicular to the atomic layers improves the characteristics of such devices, mainly due to expanding the range of parameters at which single-mode propagation can be achieved. Thus, using anisotropic materials offers new opportunities and novel control knobs when designing nanophotonic devices. info:eu-repo/grantAgreement/ES/MCIU/PID2020-Q1115221GB-C41 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 9.6 2023 CHEMISTRY, PHYSICAL 30 / 178 = 0.169 2023 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 56 / 439 = 0.128 2023 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 24 / 141 = 0.17 2023 Q1 T1 PHYSICS, CONDENSED MATTER 10 / 79 = 0.127 2023 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 29 / 231 = 0.126 2023 Q1 T1 PHYSICS, APPLIED 18 / 179 = 0.101 2023 Q1 T1 3.411 2023 Bioengineering 2023 Q1 Chemistry (miscellaneous) 2023 Q1 Nanoscience and Nanotechnology 2023 Q1 Materials Science (miscellaneous) 2023 Q1 Mechanical Engineering 2023 Q1 Condensed Matter Physics 2023 Q1 16.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Ermolaev, Georgy A.
