Tracking exceptional points above laser threshold
Kaiwen Ji, Qi Zhong, Li Ge +5
Recent studies on non-Hermitian optical systems having exceptional points (EPs) have revealed a host of unique characteristics associated with these singularities, including unidir…
Canonical Four-Wave-Mixing in Photonic Crystal Resonators: tuning, tolerances and scaling
Alexandre Chopin, Gabriel Marty, Inès Ghorbel +5
Canonical Four-Wave-Mixing occurs in a resonator with only the required number of modes, thereby inhibiting competing parametric processes. The properties of the recently introduce…
Time-correlated Photons from a InGaP Photonic Crystal Cavity on a Silicon Chip
Alexandre Chopin, Inès Ghorbel, Sylvain Combrié +3
Time-correlated photon pairs are generated by triply-resonant Four-Wave-Mixing in a InGaP Photonic Crystal cavitiy. Maximal efficiency is reached by actively compen…
Direct observation of zero modes in a non-Hermitian nanocavity array
Flore Hentinger, Melissa Hedir, Bruno Garbin +5
Zero modes are symmetry protected ones whose energy eigenvalues have zero real parts. In Hermitian arrays, they arise as a consequence of the sublattice symmetry, implying that the…
Efficient Type II Second Harmonic Generation in an Indium Gallium Phosphide on insulator wire waveguide aligned with a crystallographic axis
Nicolas Poulvellarie, Carlos Mas Arabi, Charles Ciret +7
We theoretically and experimentally investigate type II second harmonic generation in III-V-on-insulator wire waveguides. We show that the propagation direction plays a crucial rol…
Photonic Crystal Optical Parametric Oscillator
Gabriel Marty, Sylvain Combrié, Fabrice Raineri +1
Miniaturization of devices has been a primary objective in microelectronics and photonics for decades, aiming at denser integration, enhanced functionalities and drastic reduction…
