Exploring the application potential of photonics

Juejun Hu John F. Elliott Professor of Materials Science and Engineering DMSE, Massachusetts Institute of Technology (MIT) Abstract: Wide field-of-view (FOV) optics are widely deployed in imaging and sensing applications spanning consumer electronics, automotive sensing, security surveillance, photography and cinematography, medical imaging, and more. Conventional wide-FOV optics involve multiple cascaded glass lenses resulting in major size, weight and cost limitations. Metasurface optics using sub-wavelength structures for light manipulation provide a promising alternative for wide-FOV optics. In this talk, I will start by presenting an analytical design framework for wide-FOV metasurface optics, followed by discussing their experimental demonstrations in broad wave bands from visible to long-wave IR. I will show that the wide-FOV architecture can be further extended to introduce novel functionalities such as parfocal zoom and large depth-of-field imaging. Finally, I will discuss new applications of wide-FOV metasurface optics in 3-D sensing and projection display.

Geneviève Gariépy Engineer, Sun-Earth System Science, Canadian Space Agency / Government of Canada Summary: Satellite technologies play an essential role in the fight against climate change. The data needed for prediction, mitigation and adaptation are often obtained using optical instruments. In this presentation, Geneviève will share some examples of projects led by the Canadian Space Agency in this direction, and provide an overview of existing programs to participate in space developments that may be of interest to research groups and the student community.

Denis Panneton Research specialist, Institut national d'optique (INO) Abstract: Many technologies developed in the laboratory have great potential for meeting society's needs, but the challenge is sometimes to adapt them to the context in which they will be used. At INO, the aim is to innovate, i.e. to translate knowledge into concrete solutions adopted by the market. One surprising example is the use of optics and photonics in agriculture. What happens when a good idea from the lab is installed on a tractor in the middle of a broccoli field?

Yasaman Soudagar Co-founder & CEO, Neurescence Abstract: In order to understand how the brain receives information, processes this information and the resulting output, it is necessary to follow the activities of neurons in brain circuitries encompassing multiple brain regions and modulate these neurons in a determinist way to convert correlations to causal relations. In this presentation, I will discuss how optics enables such understanding of the brain function and introduce Multi-Region Miniscopes in the context of neuroscience research market, from ideation to revenue generation and highlight the most important aspects of technology development and value creation, as a startup experience and through acquisition, then integration with Bruker, as a publicly traded company.

Axis: Quantum Photonics

Bienvenu Ndagano Professor, INRS-ÉMT, Quebec MEIE Research Chair in Quantum Photonics Summary: Exploiting spatial correlations between photons is a fundamental in quantum imaging. Correlation-based imaging, a scheme whereby one photon from a pair interacts with an object before reaching the detection system. The joint measurement of the two photons then reveals the image of the object. Though the image reconstruction was initially implemented using computational techniques that employ a single pixel with no spatial resolution on its own, modern implementations can make use of arrays of single-photon sensitive detectors. Novel imaging sensors such as arrays of single photon avalanche diodes (SPADs) have enabled two- and three-dimensional imaging, the latter being enabled by the high temporal resolution. Furthermore, their high-frame rate, compared to rival technology, dramatically reduces the acquisition time required to spatially characterise quantum states and form a correlation image. In this talk, we will provide an overview of the recent developments in 2D, and 3D correlation-based imaging using photon pairs and enabled by SPAD cameras. Particularly, we will focus on optical designs geared towards applications in microscopy.

Fabio Boschini Professor, INRS-ÉMT Abstract: Time- and angle-resolved photoemission spectroscopy (TR-ARPES) is a powerful technique that provides direct access to the light-induced ultrafast dynamics of the electronic band structure of quantum materials with both momentum and energy resolutions [Boschini, Zonno, Damascelli Rev. Mod. Phys. 96, 015003 (2024)]. The TR-ARPES endstation at the Advanced Laser Light Source (ALLS) user facility offers mid-infrared optical excitation capabilities (0.15-0.8 eV range) together with a 6 eV probe (soon to be upgraded to >10 eV extreme ultraviolet via high harmonic generation). I will present new TR-ARPES results on Bi2Sr2CaCu2O8+δ (Bi2212), a prototypical high-Tc cuprate superconductor. Specifically, I will show how mid-infrared light, with photon energy well below the charge transfer gap of Bi2212, quenches the superconducting condensate over a wide momentum range.
