The student in this course will acquire: • A broad information on the optical properties of the main materials exploited in photonic devices: dielectrics, metals, semiconductors. To this aim, an extensive phenomenological treatment is provided on the Lorenz theory for the dielectric response, on the Drude theory of the metal response, and on the band-to-band interactions involved in the response of semiconductors (absorption, spontaneous emission, stimulated emission), including the qualitative behavior of quantum well structures and the related selection rules. An introductory reminder is also provided on the crystal and electronic properties of the relevant materials. • A detailed knowledge on the principles of operation of active photonic devices, including sources (LEDs, lasers), optical amplifiers (SOAs), electro-optic and electro-absorption modulators, receivers (pin and avalanche photodiodes). • A knowledge of the propagation properties of the main waveguiding structures (dielectric waveguides, plasmonic waveguides) and of the passive optical components (MMI components, coupled mode components). • A knowledge of the aspects related to the integration of optoelectronic devices (hybrid and monolithic). • The ability of evaluate the main properties of active and passive photonic devices through simplified analytical approaches • The ability of applying numerical techniques (e.g. the beam propagation method) to the analysis of complex propagating (active and passive) photonic structures.

The course requires the basic elements of semiconductor physics, electronic devices (in particular, the theory of pn junction) and of electromagnetic fields and electromagnetic wave propagation. Concepts like TE and TM propagation are re-introduced in detail for the photonic case but some basics are required.

Modalità di esame: Prova scritta (in aula); Prova orale obbligatoria; Elaborato scritto prodotto in gruppo;
Exam: Written test; Compulsory oral exam; Group essay;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Written test; Compulsory oral exam; Group essay;
The examination in based on: 1. a written test on theory (2h), consisting in the written answer to a set of questions; questions are taken verbatim from a set provided already from the beginning of the course in the web site; 2. a short oral (15 m) based on the discussion of the written part and if needed of the CAD reports / homeworks (see following point); 3. the evaluation of a CAD lab reports and of homeworks based on the solution of numerical problems (as discussed in the numerical classroom labs). The relative weight of items 1 and 2 is 4/6 while the weight of item 3 is 2/6. During the written test, no written material is allowed.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
