Tunable color emissions, emerging from a single CdTe nanowire, are demonstrated experimentally based on optical transverse nonlinear effects. The pumping light at different wavelengths (e.g., 1064 nm and 980 nm) is coupled to a nanowire at both ends via evanescent-field coupling. The light at different wavelengths (e.g., 510 nm, 532 nm, and 713 nm) can be simultaneously assessed using complex optical transverse nonlinear effects, including transverse sum-frequency generation (TSFG), transverse second-harmonic generation (TSHG), and two-photon absorption (TPA)-induced fluorescence. By changing the wavelength and the power of the pumping lights, the spectra of the transverse light emissions change as well, leading to tunable color emissions at the single-nanowire level with a Rec. 2020 coverage of ~21.6%. The results indicate the potential of transverse nonlinear effects in applications ranging from optical display and spectroscopy to communication.
