Mid-infrared-perturbed Molecular Vibrational Signatures in Plasmonic Nanocavities
Rohit Chikkaraddy, Angelos Xomalis, Lukas A. Jakob +1
Recent developments in surface-enhanced Raman scattering (SERS) enable observation of single-bond vibrations in real-time at room temperature. By contrast, mid-infrared (MIR) vibra…
Accessing Plasmonic Hotspots using Nanoparticle-on-Foil Constructs
Rohit Chikkaraddy, Jeremy J Baumberg
Metal-insulator-metal (MIM) nanogaps in canonical nanoparticle-on-mirror geometry (NPoM) provide deep-subwavelength confinement of light with mode volumes smaller than …
Detecting mid-infrared light by molecular frequency upconversion with dual-wavelength hybrid nanoantennas
Angelos Xomalis, Xuezhi Zheng, Rohit Chikkaraddy +6
Coherent interconversion of signals between optical and mechanical domains is enabled by optomechanical interactions. Extreme light-matter coupling produced by confining light to n…
