Abstract
Polaritons are half-light, half-matter quasi-particles formed by the interaction of light and different polarons. They can be applied for light-control at sub-wavelength scales and have shown intriguing potential for optical imaging, enhanced nonlinear optics and novel metamaterial design. Recent advances in the twistronics of two-dimensional van der Waals materials have enabled a vast variety of extraordinary phenomena associated with moiré physics, which also inspired new direction for the research of polaritons. In this article, we briefly review the rise of "twist-photonics", including plasmon polaritons in twisted graphene system, exciton polaritons in a twisted transition-metal dichalcogenide system and phonon polaritons in a twisted h-BN and α -MoO3 system. Twist van der Waals materials may offer new directions to manipulate light-matter interactions at nanoscale.
