Optics and Photonics

Light allows us to observe the world. In modern society, optics and photonics are vital to both industry and major research fields. Automated systems are developed for a multitude of tasks, with a growing optical sensing industry providing the information needed for an automated response. Research on single-photon interaction aims to develop new tools for quantum information processing. Super-resolution systems are pushing the limits of biological imaging.

Optics and Photonics at KTH

By studying optics and photonics, you will receive a broad knowledge of optics ranging from advanced quantum optics through photonic devices and wave optics to geometrical optics systems. A minimum of 40 credits must be chosen from core knowledge courses within the track. Among them, there are two mandatory courses, one on light propagation ( Optical physics SK2300 ) and the other on light-matter interaction ( Light-matter interaction SK2902 ). You can then choose your own direction within the field from a wide range of courses.

Courses are taught by research groups at the Department of Applied Physics, often in close relation to their research topics. For example, the Quantum-and Biophotonics unit  gives courses on quantum optics and photonics, the Photonics unit  on light-matter interaction and photonic devices, the Laser Physics group  on laser physics and spectroscopy, the  on microscopy and bionanophotonics and the Biomedical and X-ray Physics unit  on x-ray physics and applied optics.

Topics covered

You will cover the basics of optics: geometrical optics, wave optics and quantum optics or photonics. This knowledge will be put to use in a wide range of applications such as optical design, optical devices, lasers, optical fibers, nanophotonics or biomedical optics.


After completing your master’s degree on the Optics and Photonics track, both the academic and the industrial route will be open to you. Those students with an interest in research can contact the different research groups during their studies and often continue to do a PhD. Those students with interests in industry often go to research and development in optics companies. Due to increased automation, and a consequent increased need for optical sensors, the optical industry in Sweden is growing.
