Abstract
A perovskite optical element includes a light guiding unit and a luminescent layer. The light guiding unit is configured to conduct light and serves as a resonant cavity. The luminescent layer is a thin film made of perovskite material and clads the light guiding unit. The luminescent layer is configured to be excited by an excitation module to emit light. The light is conducted and output by the light guiding unit. A manufacturing method of a perovskite optical element includes preparing a dip coating solution; dipping a single crystal optical fiber in the 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; and placing the single crystal optical fiber into a tube furnace, heating the crystal optical fiber, and introducing synthetic molecules into the tube furnace.
