Silicon Carbide photonic platform based on suspended subwavelength waveguides
Francesco Garrisi, Ioannis Chatzopoulos, Robert Cernansky +1
Silicon carbide (SiC) displays a unique combination of optical and spin-related properties that make it interesting for photonics and quantum technologies. However, guiding light b…
Nanophotonic source of broadband quadrature squeezing
Robert Cernansky, Alberto Politi
Squeezed light are optical beams with variance below the Shot Noise Level. They are a key resource for quantum technologies based on photons, they can be used to achieve better pre…
High-Q/V two-dimensional photonic crystals cavities in 3C-SiC
Ioannis Chatzopoulos, Francesco Martini, Robert Cernansky +1
Solid state quantum emitters are between the most promising candidates for single photon generation in quantum technologies. However, they suffer from decoherence effects which lim…
Amplitude-Multiplexed readout of single photon detectors based on superconducting nanowires
Alessandro Gaggero, Francesco Martini, Francesco Mattioli +4
The realization of large-scale photonic circuit for quantum optics experiments at telecom wavelengths requires an increasing number of integrated detectors. Superconductive nanowir…
Second harmonic generation from strongly coupled localized and propagating phonon-polariton modes
Ilya Razdolski, Nikolai Christian Passler, Christopher R. Gubbin +8
We experimentally investigate second harmonic generation from strongly coupled localized and propagative phonon polariton modes in arrays of silicon carbide nanopillars. Our result…
Complementary metal-oxide semiconductor compatible source of single photons at near-visible wavelengths
Robert Cernansky, Francesco Martini, Alberto Politi
We demonstrate on chip generation of correlated pairs of photons in the near-visible spectrum using a CMOS compatible PECVD Silicon Nitride photonic device. Photons are generated v…
