Leti at Photonics West

Leti, an institute of CEA-Tech, will present five invited papers, 21 in total (20 oral papers and 1 poster), at Photonics West 2020 in San Francisco, Feb. 1-6. In addition, its teams will introduce the institute’s latest transfer-ready solutions for all-wavelength imaging, information display systems, light-emissive components, optical data communications, optical sensors, and other advances at the French Pavilion in booth 857A, Moscone Center, during the event.

CEA-Leti also will host a workshop and networking-cocktail reception for invited guests beginning at 5:15 p.m., Feb. 5, at the W San Francisco hotel. Presentations at the event will include a keynote entitled “Working backwards from the customer to the sensor” by Pat Tang, vice president of hardware technology and machine learning at Amazon Lab126 in Sunnyvale, Calif. The workshop, which will focus on disruptive photonics concepts for new applications and markets, will begin with introductions by Emmanuel Sabonnadière, CEA-Leti CEO, and Agnès Arnaud, head of the institute’s Optics & Photonics Division.

Workshop topics include:

  • New miniature sensors of particulate matter using angular spectral imaging, Laurent Duraffourg CEA-Leti’s photonics sensors lab manager
  • Toward miniaturized solid-state Lidar using the convergence between silicon photonics & electronics, Francois Simoens, CEA-Leti, executive strategic program manager
  • Computational microscopy, Cédric Allier CEA-Leti, Ph.D. project manager, live cell imaging
  • Low-loss silicon photonics platform for quantum technologies, Eleonore Hardy, CEA-Leti, business developer, silicon photonics

On Feb. 4-6 in booth #857A, CEA-Leti’s multidisciplinary optics-and-photonics teams will demonstrate their advances in several technologies, including:

  • NeoLed: compact, low-cost & long-lifespan, distributed-switch LEDs.
  • LensFree: an imaging technology for point-of-care analysis and pathology screening.
  • LiFi-multicell: the world’s first smart orchestrator for interference-free LiFi networks.
  • Pixcurve: technology that makes imaging or photographic products lighter and more compact.
  • Photonic sensors: toward low-cost on-chip chemical sensors.
  • Silicon photonics: design, manufacturing, testing & packaging solutions.

In addition, Scintil, a startup of CEA-Leti, will present its silicon photonic circuits with wafer-level integrated lasers at the booth.

CEA-Leti will present major scientific results this year at the BiOS and OPTO conferences.  Among the 21 papers:
