1. A manufacturing method of a perovskite optical element, comprising:
providing a single crystal optical fiber having an outer periphery with a flatness in an atomic-level;
dipping the single crystal optical fiber in a dip coating solution for one hour, removing the single crystal optical fiber out of the dip coating solution, and drying the single crystal optical fiber, wherein, during dipping the single crystal optical fiber in the dip coating solution, nanomaterials, provided in the dip coating solution, grow into crystals on the outer periphery of the single crystal optical fiber; and
placing the single crystal optical fiber into a tube furnace, heating the single crystal optical fiber, and introducing synthetic molecules into the tube furnace to form the crystals into a perovskite thin film.
