Measuring the magnetic dipole transition of single nanorods by spectroscopy and Fourier microscopy
R. Chacon, A. Leray, J. Kim +6
Rare-earth doped nanocrystals possess optical transitions with significant either electric or magnetic dipole characters. They are of strong interest for understanding and engineer…
Wavevector analysis of plasmon-assisted distributed nonlinear photoluminescence along Au nanowire antennas
Deepak K. Sharma, Adrian Agreda, Julien Barthes +3
We report a quantitative analysis of the wavevector diagram emitted by nonlinear photoluminescence generated by a tightly focused pulsed laser beam and distributed along Au nanowir…
Electrostatic control over optically-pumped hot electrons in optical gap antennas
Adrian Agreda, Sviatlana Viarbitskaya, Igor V. Smetanin +3
We investigate the influence of a static electric field on the incoherent nonlinear response of an unloaded electrically-contacted nanoscale optical gap antenna. Upon excitation by…
Effect of quantized conductivity on the anomalous photon emission radiated from atomic-size point contacts
Mickaël Buret, Igor V. Smetanin, Alexander V. Uskov +2
We observe anomalous visible to near-infrared electromagnetic radiation emitted from electrically driven atomic-size point contacts. We show that the number of photons released str…
Directional Second Harmonic Generation Controlled by Sub-wavelength Facets of an Organic Mesowire
Deepak K. Sharma, Shailendra K. Chaubey, Adarsh B. Vasista +4
Directional harmonic generation is an important property characterizing the ability of nonlinear optical antennas to diffuse the signal in well-defined region of space. Herein, we…
Biased Nanoscale Contact as Active Element for Electrically Driven Plasmonic Nanoantenna
Alexander V. Uskov, Jacob B. Khurgin, Mickael Buret +3
Electrically-driven optical antennas can serve as compact sources of electromagnetic radiation operating at optical frequencies. In the most widely explored configurations, the rad…
