Second-Harmonic Whispering-Gallery Modes in ZnO Nanotetrapod

We present the observation of second-harmonic (SH) whispering-gallery modes (WGMs) in the hexagonal cross-sections of the tapered ZnO nanotetrapod legs. Because of the continuously changing diameter in the leg, several orders of the WGMs at different SH wavelengths can be on resonance simultaneously...
