Abstract : You are invited to join Dr. Matthew Delaney for a technical and career presentation exploring the opportunities and challenges of the photonics integrated ecosystem. In the first part of the talk, Dr. Delaney will present conducted at the University of Southampton to develop and deploy new phase change materials in novel devices to create reconfigurable photonic switches, now a hot topic with the AI/data center boom. By coating a multimodal interference device (MMI) with a phase change material (PCM), and writing different pixel patterns into the PCM, it is possible to change the wavefront of the light within the MMI, enabling a fine level of control. This can be used as the basis for arbitrary photonic routing, in a small footprint and low-power device. In the second part of the talk, Dr. Delaney will provide a broader overview of the status and challenges of the integrated photonics field based on insights from working with some of the largest companies in the world across the whole application space, as they race to bring novel solutions to market. Join the presenter to debate where the field is heading. Hopefully, this will be a more interactive session where we can discuss different ideas as a group.

Abstract: In the talk I will try to convince you that the answer is yes. Maxwell postulated that there can be a current of electric charges in the vacuum. This was needed to turn the equations of electrostatics into a consistent set of quations forming the basis of electrodynamics. We argue that Maxwell’s current are moving virtual elementary particles and their anti-particles in the vacuum. We are using a phenomenological model treating the vacuum as a dielectric. We find this reproduces fairly well the coefficients and . We also formu­lated the story in the language of quantum field theory.

Early detection and efficient management of these disorders can provide significant health benefits. By providing real-time, data-driven insights AI-driven methods meet an urgent need for early detection and management of these disorders. In this talk, Prof. Phoha will present the potential of AI-driven early diagnosis and Digital Therapeutics (DTx) for neurological disorders. Using the unique properties of data generated through neurological anomalies and disorders, one can use AI methods such as transfer learning from existing knowledge; one-shot and few-shot learning for spiking and sparse data, and hidden Markov models to find underlying relationships and causes of malignant neurological disorders. The speaker will show how the generated data can be captured through smart wearables and phones, how uncovering relationships provides insights for digital rehabilitation, and how using augmented reality and virtual reality provides tremendous potential for cognitive therapy, psychiatric assessments, and rehabilitation. Prof. Phoha will outline a proof-of-concept smart diagnostics-enabled mirror and discuss security issues in smart diagnostics. Speaker(s): Prof. Vir Phoha, Dr. Vishnu S.

Montréal Quantum Photonics Seminar Series Abstract: When a pulse of light traverses a material, it incurs a time delay referred to as the group delay. Should the group delay experienced by photons be attributed to the time they spend as atomic excitations? However reasonable this connection may seem, it appears problematic when the frequency of the light is close to the atomic resonance, as the group delay becomes negative in this regime. To address this question, I used the cross-Kerr effect to probe the degree of atomic excitation caused by a resonant transmitted photon by measuring the phase shift on a separate beam that is weak and off-resonant. These results, over a range of pulse durations and optical depths, are consistent with the recent theoretical prediction that the mean atomic excitation time caused by a transmitted photon (as measured via the time integral of the observed phase shift) equals the group delay experienced by the light. Specifically, I measured mean atomic excitation times ranging from (−0.82 ±0.31)τ0 for the most narrowband pulse to (0.54 ±0.28)τ0 for the most broadband pulse. I report these times normalized to the non-post-selected excitation time τ0, which is equal to the scattering (absorption) probability multiplied by the atomic lifetime τsp. These results suggest that negative values taken by times such as the group delay have more physical significance than has generally been appreciated. Bio: Daniela Angulo is a physicist from Colombia who recently completed her PhD at the University of Toronto, focusing on experimental light-matter interaction. Under the supervision of Aephraim Steinberg, her research explored the behavior of photons in atomic clouds using weak measurements. She is passionate about teaching and science communication. Outside the lab, she is an avid cyclist and musician. Local J-1035 Pavillon J. A. Bombardier, Polytechnique Montréal, Montréal, Quebec, Canada
