2294. On-chip Fabry-Perot microcavity arrays for cavity QED (I)

Ray DeCorby (University of Alberta)

Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Invited Speaker / Conférencier(ère) invité(e)

We describe a monolithic thin-film buckling process used to fabricate arrays of high-finesse, tunable, curved-mirror Fabry-Perot cavities on a chip. Arrays of small-mode-volume cavities exhibit good uniformity and nearly reflectance-limited finesse. The process has been adapted to a variety of thin film material combinations, for operation throughout the visible and near-infrared regions. ...

2121. Coupled spatial and spectral properties of a spectrally broadband photon pair source in bulk PPLN (G)*

Mrs Aimee Gunther (Institute for Quantum Computing; Department of Physics and Astronomy, University of Waterloo)

Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

While quantum properties of light promise much-needed enhancements to metrology, further development of quantum light sources are needed to readily harness energy-time correlations for applications in imaging and spectroscopy. Spectrally broadband photon pairs, generated from the process of spontaneous parametric down-conversion (SPDC), require tight energy-time anti-correlations in order to...

2131. Improving the quality of heralded single-photon sources with cascaded downconversion

Deny R Hamel (Université de Moncton)

Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Oral (Non-Student) / Orale (non-étudiant(e))

Single photons play an important role in several quantum technologies, acting as flying qubits to transfer quantum information for both computing and communication applications. In many cases, it is acceptable for these single photons to be produced randomly, as long as they are accompanied by heralding signals announcing their creation. Such heralded single photons sources are straightforward...

2136. Photonic device for the detection of trace gases (G)

Mr Joshua Trevisanutto (Lakehead University)

12/06/2018, 14:30

Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Oral (Graduate Student) / Orale (Étudiant(e) du 2e ou 3e cycle)

A trace gas detection device has applications in environmental monitoring and healthcare. Authors will present the working principle of a trace gas sensor operating at room temperature, which was developed using the intracavity absorption spectroscopy method. In the system, a gas cell based on hollow core photonic crystal fiber (PCF) was used as an intracavity cell. The experiments were...

2315. An enhanced Kerr non-linearity using Rydberg electromagnetically induced transparency outside the blockade regime (G)

Josiah Sinclair (University of Toronto)

12/06/2018, 14:45

Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Oral (Graduate Student) / Orale (Étudiant(e) du 2e ou 3e cycle)

The strong interactions between Rydberg atoms provides an exciting platform for quantum nonlinear optics. Rydberg blockade (where a cloud of many atoms is unable to support more than a single excitation due to dipole interactions) combined with electromagnetically induced transparency (EIT) (where on-resonant absorption is suppressed due to the presence of a second coupling field) has been...
