Introduction to Optics and Photonics (34021)
This course introduces the students to classical optics and inspires them with cases of industrial applications from our own portfolio. The course is dedicated to bachelor students that do not follow the Physics and Nanotechnology line. Therefore, the course is weighting applied optics strongly. The course provides access to a line of Fotonik’s master courses in applied optics.
The course provides 5 ECTS, it includes guest speakers, industrial cases, exercises at Nanoteket and at Risø. The examination includes written exercises (40%) and a written exam (60%).
The learning objectives are split into three parts:
The first part gives the student a historical introduction to light and how it has been described through our history. Then, light is characterized in terms of its radiometric measures (SI units) and its photometric measures (impression of light seen with a human eye). Finally, a general introduction to light sources will be provided (Excitation and emission from matter, black body radiation, semiconductor light sources and lasers).
The second part consider optical materials, and how light propagates through these materials (including refraction, dispersion, absorption, scattering), and how it enters and leaves the materials (Fresnels equations). Then, lights propagation through ideal lenses and lens systems will be described, using the lens equation, real and virtual images and ray matrices. The principle of optical aberrations and energy transfer through optical systems will be discussed.
The third part considers the wave physics of light. Polarization of light (Jones vector and matrices) will be introduced. Superposition and interference of light will be introduced, and used to discuss typical interferometer and their application. We will discuss spectroscopy, using Fabry-Perot interferometry, diffractions grating or dispersion prisms, thin film interference and interferometry with coherent and partly incoherent light.
