Lecturer: G. Bolognini (CNR-IMM Researcher)
Duration: 12 hours in March and April
Programme:
The course is divided into 2 parts
Fundamentals of photonics
This course will provide an overview on fundamental principles of photonics and lightwave propagation, focusing in particular of optical fiber technologies. In its initial part, the course will also review basic theoretical principles of electromagnetism of fields and guided waves. More in detail, the course will provide an overview on lightwave systems based on optical fibers, total internal reflection principles, transverse modes. The course will then approach single- and multi-mode fibers, dealing with effects such as optical absorption and different scattering mechanisms, as well as chromatic and modal dispersion.
Photonic materials and devices
This course will provide a review of most important devices and materials for photonics, such as LED and lasers, photo-detectors, and passive opto-electronic components. The course will develop the basic concepts learned from the general course (Fundamentals of photonics). More in detail, the course will provide the core principles on light sources for optical communications (e.g. the rate equations in semiconductors and the light emitting diode - LED, the optical feedback and the laser, multi-mode and single-mode lasers), semiconductor photodetectors (p-i-n and avalanche photodiodes, heterostructures), and give a brief outline of most important passive opto-electronic components.
