Photonics

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

Teaching method

Teaching Methods

The Course of Photonics includes classroom presentation and exhibition of matter and of experimental activities classes in optics laboratory. A teaching methodology centered on the ongoing activity of the student is adopted, which includes the completion of online lessons and experimental activities and participation in the presentation of the program topics and problem solving. The classroom presentations are supported by video projection and demonstrations and simulations technological and applications are always emphasized. The teaching-learning process relies on E-Learning platform that posts all the course information, the learning units, lessons, set of experimental activities proposals within the learning units, quizzes, videos, information about relevant conferences in Photonics, catalogs of photonics components and devices manufacturers and scientific articles.

Evaluation method

Assessment Elements

•Online Activities: quizzes and lessons (AO)

•Experimental Activities: 4 to 5 experimental activities experimentais requiring full experiment preparation and programming, execution and reporting. Each report will be evaluated and assigned a mark (AE).

•Final test (T)

•Final Exam (E)

•Exclusion: access to the final exam, by carrying out with success all online and experimental activities

Grades

N Online Activities: AO=1/N∑AO_i
N Experimental Activities: AE=1/N∑AE_i
Final Test: T
Final Exam: E
Final Mark:

CF=0,15xAO+0,45xAE+0,4x(T or E)

Scales and Rounding

All ratings are given on a scale of 0 to 20 and those of the components are rounded to one decimal place and the final to units.
