The mixing of two-dimensional (2D) van der Waals supplies with nanostructures has triggered a large spectrum of optical and optoelectronic functions. Photonic constructions of standard supplies usually lack environment friendly reconfigurability or multifunctionality. Atomically skinny 2D supplies can thus generate new performance and reconfigurability for a well-established library of photonic constructions akin to built-in waveguides, optical fibers, photonic crystals, and metasurfaces, to call a couple of. In the meantime, the interplay between gentle and van der Waals supplies could be drastically enhanced as nicely by leveraging micro-cavities or resonators with excessive optical confinement. The distinctive van der Waals surfaces of the 2D supplies allow handiness in switch and mixing with varied prefabricated photonic templates with excessive levels of freedom, functionalizing because the optical acquire, modulation, sensing, or plasmonic media for numerous functions. Right here, we overview latest advances in synergizing 2D supplies to nanophotonic constructions for prototyping novel performance or efficiency enhancements. Challenges in scalable 2D supplies preparations and switch, in addition to rising alternatives in integrating van der Waals constructing blocks past 2D supplies are additionally mentioned.
