Objectives
The fundamental principles of optics are envisaged namely those relevant for applications in photonics, particularly those related with the detection of light, telecommunications, signal processing, optical and optical devices. In lab classes one aims to verify experimentally relevant principles in Photonics, and measure the optical constants of materials, with student involvement in planning of experimental activities and handling of optical instrumentation
Prerequisites
There are no particular previous courses required to enrollment in this course.
