Extreme mid-infrared field enhancement and anapoles in high-index plasmonic metamaterials
Zoltan Sztranyovszky, Nicolas Spiesshofer, Caleb Todd +5
High-refractive-index materials underpin a wide range of optical technologies, including communications, imaging, lasers, and integrated photonic systems. Here, we demonstrate a se…
Near-Field Vibrational Energy Transfer for Mid-Infrared Upconversion in Plasmonic Nanogaps
Avisekh Pal, Anju Sajan, Christopher Sumner +3
Förster energy transfer underpins modern photonics, yet establishing an analogous vibrational pathway in the mid-infrared (MIR) remains highly challenging, as sub-picosecond intram…
Mid-infrared Assisted THz Phonon Amplification in a 2D Semiconductor for Room Temperature Detection
Christopher Sumner, Jakob Ziewer, Anju Sajan +2
Efficient and selective excitation of lattice vibrations is central to controlling energy flow at the nanoscale, yet remains challenging under conventional optical excitation. Here…
