Zinc Oxide (ZnO) nanomaterials exhibit useful optical properties facilitating their photonic applications. In particular, one dimensional ZnO nanorods (NRs) have been extensively studied and engineered for better photonics, optoelectronics, and bio-sensing applications. Among various light-matter interactions occurring in ZnO NRs, we investigated a waveguiding phenomenon by imaging individual ZnO NRs by a broadband coherent Raman spectroscopic microscope. We observed different types of coherent and incoherent emissions are transported through single ZnO NRs over several micrometers. We present various optical characterization results of the waveguiding phenomenon of each photoemission type and discuss potential nanophotonics applications.
