Brief

Aaron Danner (National University of Singapore) delivers a tutorial presentation (video, 2026-06-17) on the physics and engineering of optical frequency combs. The talk provides complete derivations for electro‑optic frequency combs in lithium niobate, covers practical workflows for generating and using combs, and explains how these techniques permit measurement and metrology of THz‑range signals, drawing inspiration from the COMBS centre.

Why it matters

Aaron Danner (NUS) presents the physics and engineering of optical frequency combs, including step-by-step derivations for electro‑optic frequency combs implemented in lithium niobate.

Key details

  • The lecture connects comb technology to measuring THz‑range frequencies, showing how electro‑optic modulation and microcomb concepts (COMBS initiative) enable THz metrology and spectroscopy.
  • Video published 2026-06-17 on Aaron Danner's YouTube channel; material is tutorial-style with worked example problems and full mathematical derivations.
