A two-layer Janus TMD converts light through second harmonic generation (SHG), in which the material emits light at twice the frequency of the incoming beam (left). The SHG beam usually forms a six-pointed flower shape, but certain wavelengths of light distort it. Upper right: Symmetrical flower pattern in gray and asymmetrical SHG signal pattern in red.
