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