Welcome to the Ultrafast Photonics Laboratory

Scope

Our group performs cutting-edge research in the synthesis and manipulation of laser light at ultrashort time scales (from femtosecond to nanosecond). Our expertise lies in developing technology for laser frequency combs operating at ultra-high repetition rates. We pursue applications in next-generation optical communication systems and ultrafast precision metrology.

Specific research topics are: 
  • Microresonator frequency combs (microcombs)
  • Silicon photonics
  • Broadband coherent communications
  • Ultrafast frequency-comb metrology​​
