The article discusses the fabrication and properties of nanometer-scale gold dipole antennas designed to resonate at optical frequencies. These antennas, when illuminated with picosecond laser pulses, generate white-light supercontinuum (WLCSC) radiation in the antenna feed gap, in addition to two-photon photoluminescence (TPPL) in the antenna arms. The WLCSC emission is more than 10^3 times stronger than that from solid gold stripes of the same dimensions without a feed gap. The antennas exhibit resonance at lengths significantly shorter than half the wavelength of the incident light, which contradicts classical antenna theory but aligns with computer simulations that consider the finite metallic conductivity at optical frequencies. The study highlights the potential applications of these optical antennas in optical characterization, manipulation of nanostructures, and optical information processing. The experimental techniques used include focused-ion beam (FIB) milling for precise manufacturing and confocal microscopy for detecting the WLCSC and TPPL emissions. The results show that the WLCSC power varies with antenna length, with a maximum emission observed at a specific length, suggesting a resonance phenomenon. The near-field intensity enhancement in the feed gap of the resonant antenna is crucial for generating WLCSC, and the enhancement is more pronounced than in non-resonant antennas.The article discusses the fabrication and properties of nanometer-scale gold dipole antennas designed to resonate at optical frequencies.
