title = "Directional switching of surface plasmon polaritons by VO2-gold hybrid antennas",
abstract = "We propose a novel type of dual surface plasmon polariton (SPP) gap nano-antennas which can excite SPPs directionally and switch the direction according to the device temperature. The device consists of a vanadium dioxide (VO2)-insulator-metal resonator and a metal-insulator-metal resonator with slightly different antenna width. Phase of SPPs generated by the VO2 gap antenna changes as the temperature increases, so that interference between SPPs generated from two separated gap antennas makes its launching direction switched. In case of 624 nm wavelength, directional intensity distinction ratios of coupled SPPs are about 1:5 and 7:1 when VO2 is in insulator phase and metallic phase, respectively.",
