Nanoparticle-assisted STED nanoscopy with gold nanospheres
Nicolai T. Urban, Matthew R. Foreman, Stefan W. Hell +1
We demonstrate stimulated emission depletion (STED) microscopy with 20 nm gold nanospheres coated by fluorescent silica. Compared with previous demonstrations of STED with a hybrid…
Plasmonic nanoprobes for stimulated emission depletion microscopy
Emiliano Cortes, Paloma A. Huidobro, Hugo G. Sinclair +11
Plasmonic nanoparticles influence the absorption and emission processes of nearby emitters due to local enhancements of the illuminating radiation and the photonic density of state…
Nonlinear plasmonics at high temperatures
Yonatan Sivan, Shi-Wei Chu
We solve the Maxwell and heat equations self-consistently for metal nanoparticles under intense continuous wave (CW) illumination. Unlike previous studies, we rely on {\em experime…
Reinterpreting the magnetoelectric coupling of polarizability tensors of infinite cylinders using symmetry: a simple TM/TE view
Parry Y. Chen, Jacob Ben-Yakar, Yonatan Sivan
Recently, Strickland et al retrieved dynamic polarizabilities of infinitely long wires at oblique incidence, reporting non-zero magnetoelectric coupling, seemingly defying existing…
Temperature-dependent permittivity of annealed and unannealed gold films
Po-Ting Shen, Yonatan Sivan, Cheng-Wei Lin +3
Due to local field enhancement and subwavelength confinements, nano-plasmonics provide numerous novel applications. Simultaneously, as an efficient nanoscale heat generator from in…
Coupled-mode theory for electromagnetic pulse propagation in dispersive media undergoing a spatio-temporal perturbation - exact derivation, numerical validation and peculiar wave mixing
Y. Sivan, S. Rozenberg, A. Halstuch
We present an extension of the canonical coupled mode theory of electromagnetic waves to the case of pulses and spatio-temporal perturbations in complex media. Unlike previous atte…
