Optical and photonic technologies

Head of the Division: Prof. Miroslav Hrabovský, DrSc.

Scientific focus of the division:

• Design, construction and quality-control of specialized optical components for applications in the industry and large scientific collaborations (e.g., The Pierre Auger Observatory)
• Development of methods and devices for the production, detection, and characterization of weak photon fields and for the transmission and processing of quantum information
• Development of methods for deposition and characterization of thin layers using methods of plasma deposition and vacuum steaming
• Optical non-contact measurement methods based on speckle-field and white-light interferometry, or moiré topography
• Laser welding, cutting and surface treatment
