Unidirectional single-photon emission from germanium-vacancy zero-phonon lines: Deterministic emitter-waveguide interfacing at plasmonic hot spots
Hamidreza Siampour, Ou Wang, Vladimir A. Zenin +10
Striving for nanometer-sized solid-state single-photon sources, we investigate atom-like quantum emitters based on single germanium vacancy (GeV) centers isolated in crystalline na…
Ultra-thin titanium nitride films for refractory spectral selectivity
Alexander S. Roberts, Manohar Chirumamilla, Deyong Wang +4
We demonstrate a selectively emitting optical Fabry-Pérot resonator based on a few-nm-thin continuous metallic titanium nitride film, separated by a dielectric spacer from an optic…
Laser writing of bright colours on near-percolation plasmonic reflector arrays
Alexander S. Roberts, Sergey M. Novikov, Yuanqing Yang +5
Colouration by surface nanostructuring has attracted a great deal of attention by the virtue of making use of environment-friendly recyclable materials and generating non-bleaching…
Ultra-compact graphene plasmonic photodetector with the bandwidth over 110GHz
Yunhong Ding, Zhao Cheng, Xiaolong Zhu +7
Graphene-based photodetectors, taking advantage of high carrier mobility and broadband absorption in graphene, have recently experienced rapid development. However, their performan…
