Spin waves in micro-structured yttrium iron garnet nanometer-thick films
Matthias B. Jungfleisch, Wei Zhang, Wanjun Jiang +8
We investigated the spin-wave propagation in a micro-structured yttrium iron garnet waveguide of nm thickness. Utilizing spatially-resolved Brillouin light scattering microsco…
Evaluation of defects in cuprous oxide through exciton luminescence imaging
Laszlo Frazer, Erik J. Lenferink, Kelvin B. Chang +3
The various decay mechanisms of excitons in cuprous oxide (Cu2O) are highly sensitive to defects which can relax selection rules. Here we report cryogenic hyperspectral imaging of…
Highly tunable ultra-narrow-resonances with optical nano-antenna phased arrays in the infrared
Shi-Qiang Li, Wei Zhou, Peijun Guo +6
We report our recent development in pursuing high Quality-Factor (high-Q factor) plasmonic resonances, with vertically aligned two dimensional (2-D) periodic nanorod arrays. The 2-…
Broadband resonances in ITO nanorod arrays
Shi-Qiang Li, Kazuaki Sakoda, John B. Ketterson +1
In the nanophotonics community, there is an active discussion regarding the origin of the selective absorption/scattering of light by the resonances with nanorod arrays. Here we re…
Electrical Characteristics of Superconducting-Ferromagnetic Transistors
Ivan P. Nevirkovets, Oleksandr Chernyashevskyy, Georgy V. Prokopenko +2
We report experimental results on characteristics of SFIFS junctions and multi-terminal SFIFSIS devices (where S, I, and F denote a superconductor (Nb), an insulator (AlOx), and a…
Photoionization cross section of 1s orthoexcitons in cuprous oxide
Laszlo Frazer, Kelvin B. Chang, Kenneth R. Poeppelmeier +1
We report measurements of the attenuation of a beam of orthoexciton-polaritons by a photoionizing optical probe. Excitons were prepared in a narrow resonance by two photon absorpti…
