Seminar: Mid-IR Nanophotonics: Fundamentals & Challenges – Overview
- Overview
Light in the mid-infrared (MIR) spectral region (around 2 to 20 µm) is crucial for our lives since it cools our planet and enables modern molecular spectroscopy "fingerprint" technologies for chemical recognition in labs, industries, agriculture and mining. Unique applications range from astronomy (e.g., black-hole mass assessment) to powering the nano-lithography needed for next-generation chips and near-field nanoscopes that may help characterize living cells.
In this seminar, we offer contributions that start from (i) selected fundamentals of mid-infrared photonics (light generation, optical components, modulation, detection, ...) to demonstrate (ii) a specific application such as thermography, optical communication, meteorology, astronomy, and spectroscopy both in the far-field (FTIR) and near-field (SNOM) regimes — or the other way round.
