Join the OSA Nonlinear Optics Technical Group for this webinar featuring Andrea Blanco-Redondo, head of the silicon photonics department at Nokia Bell Labs, reviewing their work on nonlinear and topological photonics in silicon. In the first part of the webinar, Dr. Blanco-Redondo will unveil their latest results on the recently discovered pure-quartic solitons, including their demonstration of the first pure-quartic soliton laser and its new energy-width scaling law. Dr. Blanco-Redondo will also provide new insights on how to leverage high-order dispersion in nonlinear applications.

In the second part, the webinar will cover recent developments in topological quantum photonics with emphasis on our experimental demonstration of nonlinearly-generated and topologically protected photon pairs and path-entangled biphoton states in silicon waveguide arrays. Finally, Dr. Blanco-Redondo will detail their latest experiments unveiling entanglement between topologically distinct modes, highlighting topology as an entanglement degree of freedom.

Subject Matter Level: Intermediate - Assumes basic knowledge of the topic

What You Will Learn:

  • What are pure-quartic solitons, how to generate them in integrated photonics and fiber platforms, and, more generally, how to leverage high-order dispersion in nonlinear applications such as ultrafast lasers or frequency combs
  • How lattice topology can protect quantum states of light and contribute to generate more complex entangled states in the context of silicon photonics quantum platforms

Who Should Attend:

  • Scientists interested in nonlinear and topological photonics
  • Researchers working in integrated photonics and ultrafast fiber lasers
  • Scientists with an interest on silicon photonics quantum experiments
