We examine multiphoton-produced optical signals waveguided through single ZnO nanorod (NR) using a newlydeveloped, scanning offset-emission hyperspectral microscopy (SOHM) technique. SOHM acquires spectrally indexedand spatially resolved intensity maps/spectra of waveguided light intensity, while excitation/emission collectionpositions and light polarization are scanned. Hence, the powerful measurement capabilities of SOHM enable quantitativeanalyses of the different ZnO NR waveguiding behaviors specific to the multiphoton-generated emissions as a functionof measurement position, and the optical origin of the guided signal. We subsequently reveal the distinct waveguidingbehaviors of single ZnO NRs pertaining to the variously originated signals and discuss particularly attractive ZnO NRproperties in CARS waveguiding. In this talk, I will present the distinctive CARS waveguiding nature through single ZnONR, exhibiting high position and polarization-dependence.
