Lead halide perovskites have seen a stellar rise in popularity in particular in form of polycrystalline thin films used in solar cells. In their Communication (DOI: 10.1002/anie.201703786), Q. Bao, U. Bach et al. describe a simple solution-based method to produce single-crystalline perovskite platelets from the precursor (MA)[PbBr3]⋅DMF. Arbitrary perovskite shapes such as arc waveguides were fabricated and employed to build active electro-optical modulators that achieve >98 % modulation intensity of wave-guided light.
