Photonics Laboratory of Munich University of Applied Sciences  

at the Department of Applied Sciences and Mechatronics 

 

The Photonics Laboratory develops and evaluates high precision optical fiber sensors that are especially adapted to the demands in medicine, industry and research.

  • Lectures in optoelectronics and fiber optic technology in the Bachelor and Master programs.
  • Research activities in optical fiber sensing based on fiber Bragg gratings (FBGs):
    • High-temperature annealing, calibration and sensing
    • Strain measurements of cartilage tissue
    • Hydrogen detection with Palladium-coated FBGs
    • Fiber-optic smart casts with embedded FBG sensors
  • Degree theses (Bachelor and Master) and doctoral theses (cooperative doctorate) in the field of fiber sensing.
  • Commissioned research for industrial partners


 		The Günther Paul Scholarship is intended to support outstanding students with an interest in optics and photonics, particularly from the second educational pathway. The Günther Paul Scholarship was awarded for the first time in 2024’. Further information Günther Paul Scholarship (hm.edu)
