Phase-Transition-Driven Hyperbolic Optical Response and Directional Polaritons in Epitaxial VO2 Thin Films
Maria Chiara Paolozzi, Annalisa D Arco, Ilaria Martinelli +10
Optical anisotropy in crystalline solids enables direction-dependent light-matter interactions and underpins a variety of advanced photonic functionalities. In this context, Vanadi…
Dual Optical Hyperbolicity of PdCoO and PdCrO Delafossite Single Crystals
Salvatore Macis, Annalisa DArco, Eugenio Del Re +12
Hyperbolic materials exhibit a very peculiar optical anisotropy with simultaneously different signs of the dielectric tensor components. This anisotropy allows the propagation of e…
Optimization of highly circularly polarized thermal radiation in -MoO/-GaO twisted layers
Marco Centini, Chiyu Yang, Maria Cristina Larciprete +2
We investigate a bi-layer scheme for circularly polarized infrared thermal radiation. Our approach takes advantage of the strong anisotropy of low-symmetry materials such as -Ga…
Large-area polycrystalline -MoO3 thin films for IR photonics
Maria Cristina Larciprete, Daniele Ceneda, Chiyu Yang +8
In recent years, excitation of surface phonon polaritons (SPhPs) in van der Waals materials received wide attention from the nanophotonics community. Alpha-phase Molybdenum trioxid…
Hybrid Thermal Yagi-Uda Nanoantennas for Directional and Narrow Band Long-wavelength IR Radiation Sources
Marco Centini, Maria Cristina Larciprete, Roberto Li Voti +3
We investigate the possibility of spatially and spectrally controlling the thermal infrared emission by exploitation of the Yagi-Uda antenna design. Hybrid antennas composed of bot…
Fabrication of GaN/AlGaN 1D photonic crystals designed for nonlinear optical applications
T. Stomeo, G. Epifani, V. Tasco +8
In this paper we present a reliable process to fabricate GaN/AlGaN one dimensional photonic crystal (1D-PhC) microcavities with nonlinear optical properties. We used a heterostruct…
