Applications of optically and electrically driven nanoscale bowtie antennas

Optical antennas play an important role in optical field manipulation. Among them, nanoscale bowtie have been extensively studied for its high confinement and enhancement. In this mini-review, we start with a brief introduction of underlying physics. Then review the applications respect to optically electrically excited antennas. Optically driven enable set such as near-field imaging/trapping, nonlinear response, nanolithography, photon generation detection. Finally, put emphasis on principle antennas, emerging method generating ultrafast broadband tunable nanosources. word, still great potential research value explore.
