Energy correlations of photon pairs generated by a silicon microring resonator probed by Stimulated Four Wave Mixing

Matteo Galli, Christophe Marcel Georges Galland, Davide Grassani

Compact silicon integrated devices, such as micro-ring resonators, have recently been demonstrated as efficient sources of quantum correlated photon pairs. The mass production of integrated devices demands the implementation of fast and reliable techniques ...

Thresholdless Lasing of Nitride Nanobeam Cavities on Silicon

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Ian Michael Rousseau, Noelia Vico Triviño, Gordon Jens Callsen

We present a temperature dependent optical and quantum-optical characterization of close-to-ideal lasing in GaN-based nanobeam cavities. Measuring the photon statistics of emission allows us to prove high-beta lasing at room temperature, and thresholdless ...

Near-Field Integration of a Si3N4 Nanobeam and a SiO2 Microcavity for Heisenberg-Limited Displacement Sensing

Tobias Kippenberg, Dalziel Joseph Wilson, Ryan Daniel Schilling, Vivishek Sudhir, Amir Hossein Ghadimi

A single-chip radio-frequency optomechanical system, consisting of a Si3N4 nanobeam in the evanescent near-field of a SiO2 optical microdisk resonator realizes displacement imprecision >30dB below the standard quantum limit at room-temperature. ...

GaN-based photonic crystal cavities on silicon for visible and near infrared applications

Noelia Vico Triviño

Photonic crystal (PhC) cavities combine ultra-high quality (Q) factors with small mode volumes, resulting in an enhancement of the light-matter interaction at the nanoscale, which, beyond fundamental studies is advantageous for countless applications in ph ...

An all-silicon single-photon source by unconventional photon blockade

Vincenzo Savona, Hugo Pierre Alexandre Flayac

The lack of suitable quantum emitters in silicon and silicon-based materials has prevented the realization of room temperature, compact, stable, and integrated sources of single photons in a scalable on-chip architecture, so far. Current approaches rely on ...
