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

III-V semiconductor photonic devices, including solar cells and photonic power converters, have superior conversion efficiencies compared to their silicon counterparts. However, high material costs limit widespread use. Light trapping strategies such as nanoscale surface texturing can enhance absorption and improve device performance. In this work, a 3D optical model was employed to...

678. Diffusion of light-driven bacteriorhodopsin nanodiscs

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

This project investigates bacteriorhodopsin (bR) embedded in lipid nanodisks as a potential light-activated nanoscale motor. Bacteriorhodopsin pumps ions when exposed to light, which we hypothesize will act as a source of propulsion for the nanodisks, in addition to their Brownian diffusion. We construct bR-nanodisk “particles” and study their motions in the absence and presence of light....

755. Photoactive Silver Nanoclusters with Optically Switchable Ligands for Organic Solar Cell Applications

Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

Different from inorganic thin-film solar cells relying on stacked donor (p-type doped) and acceptor (n-type doped) layers of the same material, the photoactive layer of polymeric organic photovoltaics (OPVs) make use of two distinct polymer donor and molecular acceptor materials. These are mixed at the nanoscale in a bulk heterojunction thin film to capitalize on the very fast relaxation rates...

826. Design and Behavior of Multistack Layer–Based Spaceplates

Yaryna Mamchur (University of Ottawa)

Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

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

The physical size of optical imaging systems is one of the greatest constraints on their use, limiting the performance and deployment of a range of systems from telescopes to mobile phone cameras. Spaceplates are nonlocal optical devices that compress free-space propagation into a shorter distance, paving the way for more compact optical systems, potentially even thin flat cameras. Here, we...

836. A Tunable Platform for Writing Multiplexed Volume Holograms

Simon Lamontagne (University of Ottawa)

Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

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

Within both science and industry, volume holograms have found countless applications; examples include data storage, signal processing and structured light generation. In practice, a hologram is produced by the interference of two light waves (reference and object) on a photosensitive medium. The resulting interference pattern is imprinted onto the medium as a modulation in its refractive...

838. Dispersion Profile Engineering for Quantum Communication via Optical Solitons and Integrated Microresonators

Zara Tehrani (Carleton University)

Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

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

Optical solitons and microresonator frequency combs offer a powerful platform for quantum communication, but their performance is critically determined by the underlying dispersion profile of the guiding structure. This work explores dispersion engineering strategies for integrated waveguides and ring resonators to realize controlled anomalous group-velocity dispersion suitable for soliton...
