Abstract: Various embodiments may provide a device for providing a first optical light of a first wavelength and a second optical light of a second wavelength. The device may include a halide perovskite structure including a first pattern and a second pattern different from the first pattern, so that the first pattern is configured to provide the first optical light of the first wavelength and the second pattern is configured to provide the second optical light of a second wavelength different from the first wavelength, upon a light incident on the first pattern and the second pattern. The halide perovskite structure may include a halide perovskite material.
