This exam is present in the following Optional Group

Objectives

Generals
The aim of the course is to provide the student with an understanding of the principles of operation of
active optical devices based on the interaction of light with nanoscale systems; it also wants to provide an
understanding of the most current laser design and construction techniques (q-dots, photonic crystal laser)
and their uses in the field of optoelectronics, quantum information and also in diagnostics that use
miniaturized optical sources

Specifics
• Knowledge and understanding: know analytical methods to understand how lasers work in various fields,
as well as know the basic technology of quantum electronics
• Ability to apply knowledge and understanding: apply analysis and learning methodologies, through
activities also in the laboratory.
• Critical and judgmental skills: tests are carried out

• Communication skills: knowing how to describe what has been learned in the field of knowledge of
technologies operating laser devices. The communication skills are realized by addressing some
fundamental topics with the request for active participation in the solution of problems, based on the
knowledge acquired from previous lessons or from courses already passed.
• Ability to continue the study independently throughout life: ability to continue subsequent studies
concerning advanced themes of photonics and quantum electronics, based on the acquired analysis and
project methodologies.

Study modes

In the classroom and on line. A first part of the course includes introductory and general topics (10 hours). A second part is the application of introductory concepts to particular cases (40 hours) and a third part with more specific topics, including laboratory experiences (10 hours).

Exam modes

The exam will take place by:
A) a brief dissertation (in oral or written form) on a topic selected by the student. It is advisable to choose the topic together with a colleague of the course and then develop two different in-depth analyzes of the same subject. The work can be presented or as a written short thesis or by slide.
B) an oral exam in which the essay and the written test will be discussed.

Overall, the text aims to verify that the students acquired knowledge and understanding of the information given during the lessons, not only from the theoretical point of view, but also referring to simulated practical situations. The students’ capability of autonomous learning is also tested, e.g., by proposing supplementary research material. Capability and autonomy to make judgements and propose solutions to simulated practical problems proposed by the teacher are verified. Finally, the communication skills are verified – within the limitation imposed by the English language which may be that not “naturally” used by the student.

To achieve a score of 30/30 cum laude, the student must show that he has acquired an excellent knowledge of all the topics taken during the course and to know how to exhibit them logically and consistently.
