Plasmonic devices – tiny plasmonic hybrid receivers
Optics ExpressPlasmonic hybrids are introduced to replace photonic optical hybrids for coherent reception. These plasmonic circuits offer a compact footprint and a fabrication compatible with many electronic platforms as one only relies on metallic layer stacks. To mitigate the plasmonic losses, we propose new designs with shortest propagation paths.

Integrated Plasmonics: Broadband Dirac Plasmons in Borophene [PDF]
Physical Review Letters, 2020 The past decade has witnessed numerous discoveries of two-dimensional (2D) semimetals and insulators, whereas 2D metals are rarely identified. Borophene, a monolayer boron sheet, has recently emerged as a perfect 2D metal with unique structure and electronic properties.

Nonlinear thermal lensing of high repetition rate ultrafast laser light in plasmonic nano-colloids
Nanophotonics, 2022 We report on experimental observations of phenomenological self-trapping in plasmonic colloids of varying plasmon peaks in the visible/near infrared. A femtosecond (fs) oscillator is used in both pulsed (35 fs, 76 MHz) and continuous wave (cw) operation ...

Semiconductor Quantum Plasmonics [PDF]
Physical Review Letters, 2019 We investigate the frontier between classical and quantum plasmonics in highly doped semiconductor layers. The choice of a semiconductor platform instead of metals for our study permits an accurate description of the quantum nature of the electrons constituting the plasmonic response, which is a crucial requirement for quantum plasmonics.
