Cascaded four-wave mixing in tapered plasmonic nanoantenna
I. S. Maksymov, A. E. Miroshnichenko, Yu. S. Kivshar
We study theoretically the cascaded four-wave mixing (FWM) in broadband tapered plasmonic nanoantennas and demonstrate a 300-fold increase in nonlinear frequency conversion detecte…
Tapered Yagi-Uda Nanoantennas for Broadband Unidirectional Emission
Isabelle Staude, Ivan S. Maksymov, Manuel Decker +4
We demonstrate experimentally the operation of tapered Yagi-Uda nanoantennas for broadband unidirectional emission enhancement. The measured transmittance spectra show that, in com…
Plasmonic Nanoantennas for Efficient Control of Polarization-Entangled Photon Pairs
Ivan S. Maksymov, Andrey E. Miroshnichenko, Yuri S. Kivshar
We suggest a novel source of polarization-entangled photon pairs based on a cross-shaped plasmonic nanoantenna driven by a single quantum dot. The integration of the nanoantenna wi…
Optical Yagi-Uda nanoantennas
Ivan S. Maksymov, Isabelle Staude, Andrey E. Miroshnichenko +1
Conventional antennas, which are widely employed to transmit radio and TV signals, can be used at optical frequencies as long as they are shrunk to nanometer-size dimensions. Optic…
Actively tunable optical Yagi-Uda nanoantenna with bistable emission characteristics
Ivan S. Maksymov, Andrey E. Miroshnichenko, Yuri S. Kivshar
We suggest and study theoretically a novel type of optical Yagi-Uda nanoantennas tunable via variation of the free-carrier density of a semiconductor disk placed in a gap of a meta…
