Objectives

Understand light matter interaction. Describe the characteristics that lead to particular optical properties of materials, be it natural or man-made. Understand the functioning of devices based on those properties.

Learning outcomes and competences

Achieving these goals will enable the student to obtain a core competence, namely: (a) understanding of operating devices, systems and experimental techniques, (b) ability to design, implement and optimize optical systems and devices, (c) Capacity to work in an environment of experimental science or in a business environment focused in particular on advanced technology.

Apart from the technical side, this course will also help to complement the training in physics and technology students.

Eligibility for exams

Attendance to at least 3/4 of classes.

Calculation formula of final grade

Assessement: continuous evaluation with final exam. The evaluation has two components:

1. final exam (X; weight 70%)
2. Presentation of a scientific paper related to the syllabus (Y; weight 30%)

Formula for the final mark: final exam (X); presentations and discussion of the monography (Y);  Final mark: F=0.7*X+0.3*Y.

For the consideration of the second component of assessment, the mark of the final exam can not be less than 8,0. Final Mark calculations: F= 0.7*X+0.3*Y.

Classification improvement

Only by final exam.
