Paper Abstract

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