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.

The seminar will focus on a range of topics related to mid-IR photonics, which will be covered in presentations given by the participating students as well as in special lectures.


Possible topics that we will cover are given below (together with some examples of relevant mid-IR technologies).

  • Infrared imaging of the black hole in our galaxy, Nobel Prize 2020 (bolometer camera)
  • Thermal imaging and night vision systems for materials testing, electronics, and medicine
  • Fundamentals of vibrational spectroscopy
  • The role of infrared radiation in earth's cooling (Michelson interferometer and bolometer)
  • Mid-IR spectroscopy for analyzing physiological processes, protein modifications in living cells (MCT detector)
  • Mid-IR nanoscopy of cells (s-SNOM)
  • Infrared light generation (globars, synchrotron, broadband laser sources, quantum cascade lasers)
  • Remote pollution sensing (dual frequency comb spectroscopy)
  • Hyperspectral earth mapping for detecting crops, minerals, etc.
