Single photons from dissipation in coupled cavities

Vincenzo Savona, Hugo Pierre Alexandre Flayac

We propose a single-photon source based on a pair of weakly nonlinear optical cavities subject to a one-directional dissipative coupling. When both cavities are driven by mutually coherent fields, sub-Poissonian light is generated in the target cavity even ...

Proposal for an Optomechanical Bell Test

Christophe Marcel Georges Galland

Photons of a laser beam driving the upper motional sideband of an optomechanical cavity can decay into photon-phonon pairs by means of an optomechanical parametric process. The phononic state can subsequently be mapped to a photonic state by exciting the l ...

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 ...

Two-dimensional polymer grating and prism on Bloch surface waves platform

Hans Peter Herzig, Elsie Barakat, Libo Yu, Joab Di Francesco

A one-dimensional photonic crystal sustaining Bloch Surface Waves (BSWs) is used as a platform for two-dimensional integrated optics. The dielectric platform shows low loss, long propagation distance and high surface field enhancement. In order to study th ...

Large-scale silicon photonic switches with movable directional couplers

Niels Quack

Fast optical circuit switches (OCSs) with high port count offer reconfigurable bandwidth in optical networks and have the potential to significantly increase the performance and efficiency of modern datacenters. In this paper, we report on a new type of in ...

Wide-band slow light in compact photonic crystal coupled-cavity waveguides

Vincenzo Savona, Momchil Minkov

Slow light has a variety of applications, in particular for enhanced nonlinear effects like four-wave mixing and high-harmonic generation. Here, we propose a photonic crystal coupled-cavity waveguide with an ultracompact arrangement of the constituent cavi ...

Remote macroscopic entanglement on a photonic crystal architecture

Vincenzo Savona, Hugo Pierre Alexandre Flayac, Momchil Minkov

The outstanding progress in nanostructure fabrication and cooling technologies allows what was unthinkable a few decades ago: bringing single-mode mechanical vibrations to the quantum regime. The coupling between photon and phonon excitations is a natural ...

Highly Scalable Digital Silicon Photonic MEMS Switches

Niels Quack

Optical circuit switches with fast switching times can provide rapidly reconfigurable bandwidth in data center networks. Silicon photonic switches are attractive candidates with their fast response times and CMOS process compatibility. In this paper, we re ...

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 ...

Large-Port-Count MEMS Silicon Photonics Switches

Niels Quack

Highly integrated optical circuit switch (OCS) with large port counts (~100x100) is achievable by combining silicon photonics and MEMS technologies. We will review the design trade-offs, performance scaling, and the current state of the art. ...
