Teaching language

Suitable for English-speaking students

Objectives

It is sought with this course: a) Develop competences and knowledge that foster research and evelopment activity, in particular those that facilitate reading and understanding the available literature and expand the needed knowledge  in a systematic and autonomous fashion; b) Understand light matter interaction; c) Describe the characteristics that lead to particular optical properties of materials, be it natural or man-made; d) Understand the functioning of devices based on those properties.

Learning outcomes and competences

Achieving these goals will enable the student to obtain a core of competences, 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. solving of 3 homework problems (Y; weight 30%)

Formula for the final mark: final exam (X); homework (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

Improvement of the final grade (at all exam periods) will respect only to the part corresponding to the final examination paper.
