  • Subcommittee

    CLEO®/Europe Focus Meeting

  • Day & Time

  • Location

    Room Boston

  • Description

    In this workshop, we will be discussing the last trends and advancements of optical frequency combs, spanning a broad frequency range from NIR to THz, with an on-chip twist. Several approaches to comb generation (fiber-based, Kerr combs, QCLs and ICLs, non-linear conversion,  supercontinuum…. ) and characterization will be presented. Themes such as soliton formation, spectroscopic applications, device integration as well as hybrid approaches to comb operation will be debated. The workshop will feature 15 minutes-long presentations from the individual panelists as well as a final, half-hour long Q&A panel interactive session to promote discussion and exchange views on the different proposed approaches.
