Surface phonon polariton resonance imaging using long-wave infrared-visible sum-frequency generation microscopy
Riko Kiessling, Yujin Tong, Alexander J. Giles +5
We experimentally demonstrate long-wave infrared-visible sum-frequency generation microscopy for imaging polaritonic resonances of infrared (IR) nanophotonic structures. This nonli…

Imaging of anomalous internal reflections of hyperbolic phonon-polaritons in hexagonal boron nitride
Alexander J Giles, Siyuan Dai, Orest J Glembocki +10
We use scanning near-field optical microscopy to study the response of hexagonal boron nitride nanocones at infrared frequencies, where this material behaves as a hyperbolic medium…
