Multi-resonant non-dispersive infrared gas sensing: breaking the selectivity and sensitivity tradeoff
Emma R. Bartelsen, J. Ryan Nolen, Christopher R. Gubbin +8
In applications such as atmospheric monitoring of greenhouse gases and pollutants, the detection and identification of trace concentrations of harmful gases is commonly achieved us…
Electrical Generation of Surface Phonon Polaritons
Christopher R. Gubbin, Simone De Liberato
Efficient electrical generation of mid-infrared light is challenging because of the dearth of materials with natural dipole-active electronic transitions in this spectral region. O…
Polaritonic quantisation in nonlocal polar material
Christopher R. Gubbin, Simone De Liberato
In the Reststrahlen region, between the transverse and longitudinal phonon frequencies, polar dielectric materials respond metallically to light and the resulting strong light-matt…
Quantum theory of longitudinal-transverse polaritons in nonlocal thin films
Christopher R. Gubbin, Simone De Liberato
When mid-infrared light interacts with nanoscale polar dielectric structures optical phonon propagation cannot be ignored, leading to a rich nonlocal phenomenology which we have on…
Nonlocal Scattering Matrix Description of Anisotropic Polar Heterostructures
Christopher R. Gubbin, Simone De Liberato
Polar dielectrics are a promising platform for mid-infrared nanophotonics, allowing for nanoscale electromagnetic energy confinement in oscillations of the crystal lattice. We rece…
Nonlocal Response of Polar Nanostructures
C. R. Gubbin, S. De Liberato
Polar dielectric nanoresonators can support hybrid photon-phonon modes termed surface phonon polaritons with lengthscales below the diffraction limit. In the deep sub-wavelength re…
