Photonic nanorod heterodimers, comprising different materials, are numerically optimized to suppress the radiation from a sandwiched visible-light source. The employed media are taken from a long list that includes most common dielectrics, semiconductors, and metals; accordingly, the obtained shielding performances constitute limits for the considered simple setup when working at the regarded wavelength bands. Therefore, the reported optimal dimers, operated at various colors of the visible spectrum, provide the design process with additional degrees of freedom; they can be critical in satisfying additional constraints when fabricating photonic devices, such as optical switches, sensors, and nanolasers.
