Van der Waals materials are of great promise for photonics and optoelectronics. Here we discuss the use of high refractive index transition metal chalcogenides, such as MoS2, and hexagonal boron nitride for nanophotonics. We present our theoretical and experimental studies of a range of devices and components made of these materials, including waveguides, resonators, and metasurfaces. We demonstrate that these van der Waals materials allow extreme optical field confinement in deeply subwavelength structures. Our studies suggest that smaller and more efficient devices may be created with the use of van der Waals materials.
