The mixing of two-dimensional (2D) van der Waals supplies with nanostructures has catalyzed a large spectrum of optical and optoelectronic purposes. Photonic buildings of standard supplies sometimes lack environment friendly reconfigurability or multifunctionality. The atomically skinny 2D supplies can thus infuse new performance and reconfigurability to the well-established library of photonic buildings reminiscent of built-in waveguides, optical fibers, photonic crystals, and metasurface, to call a number of. In the meantime, the interplay between mild 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 the 2D supplies allows handiness in switch and mixing with numerous prefabricated photonic templates with excessive levels of freedom, functionalizing because the optical achieve, modulation, sensing, or plasmonic media for numerous purposes. Right here we overview current advents on synergizing 2D supplies to nanophotonic buildings for prototyping novel performance or efficiency enhancements. Challenges on scalable 2D supplies preparations and switch, in addition to rising alternatives in integrating van der Waals constructing blocks past 2D supplies are additionally mentioned.
