Abstract：Moiré superlattces in two-dimensional vander Waals heterostructures exhibit a wealth of physical phenomena，significantly expanding the research scope of twistoptics.By precisely tuning the interlayer twist angle， Moiré superlatticescan generate unique electronic，excitonic，and optical properties，such as band flattening，strong correlationstates，topological states，and chiral optical responses.These characteristics open new opportunities for noveloptoelectronic devices，single-photon sources，exciton lasers，andquantum computing platforms.This review systematically summarizes recent advances in twisted photonics ofMoiré superlattices，covering the fabrication methods，excitonbehaviors，nonlinearoptical efects，nanoscale spectroscopy，and electricfieldtunability.Thepotential applications in future optoelectronics and quantum technologies are also discussed.

Key Words：Moiré superlattices； twistoptics；Moiré exciton；nonlinear optics；quantum optics
