Obiettivi dell'insegnamento
This course introduces the students to light-matter interactions in semiconductor micro- and nano-structures and metallic nanostructures.
Purpose of the course is the study of the effects of electron and light confinement on the optical properties of materials.
After a basic review of waves (electromagnetic and quantum mechanical) and semiconductors, various approaches to confine these waves will be described. Examples of devices employing such confinement will be considered.
Particular attention will be devoted to the generation of light in semiconductors: spontaneous and stimulated emission, lasers, and light emitting diodes will be dealt with. Starting from a general description of the physics of lasers, the evolution from diode lasers to the last generation of nanotechnological (quantum cascade) lasers will be detailed.This will be complemented by the description of the most commonly employed fabrication technologies.
Finally, as an example of subwavelength optical confinement, plasmonics and some of its applications will be discussed.
