Boosting Optical Nanocavity Coupling by Retardation Matching to Dark Modes
Rohit Chikkaraddy, Junyang Huang, Dean Kos +5
Plasmonic nano-antennas can focus light to nanometre length-scales providing intense field enhancements. For the tightest optical confinements (0.5-5 nm) achieved in plasmonic gaps…
Giant mid-IR resonant coupling to molecular vibrations in sub-nm gaps of plasmonic multilayer metafilms
Rakesh Arul, David Benjamin-Grys, Rohit Chikkaraddy +5
Nanomaterials capable of confining light are desirable for enhancing spectroscopies such as Raman scattering, infrared absorption, and nonlinear optical processes. Plasmonic superl…
Single-molecule mid-IR detection through vibrationally-assisted luminescence
Rohit Chikkaraddy, Rakesh Arul, Lukas A. Jakob +1
Room temperature detection of molecular vibrations in the mid-infrared (MIR, =3-30m) has numerous applications including real-time gas sensing, chemical reactivity, medical…
