Tuesday, August 15, 2023

An optical frequency comb (OFC) [1] is an optical signal that has a comb-like emission line spectrum on the frequency axis and is used for optical frequency measurement and precise frequency conversion from light to microwave.

Key Points: 
  • An optical frequency comb (OFC) [1] is an optical signal that has a comb-like emission line spectrum on the frequency axis and is used for optical frequency measurement and precise frequency conversion from light to microwave.
  • On the other hand, as the EO comb moves away from the seed light source on the frequency axis, microwave noise is superimposed and the frequency becomes unstable, so the frequency must be stabilized.
  • NTT and Tokyo Denki University have been researching technology to stabilize the frequency of EO comb [8].
  • Applications of optical frequency measurement:
    As a stabilized EO comb application, NTT focused on absolute optical frequency measurement technology and determined the optical frequency fs of the seed light source.
