The course is meant to allow the PhD students to have a direct “hands-on” experience in a real experimental laboratory on fiber optics transmission, thanks to the infrastructure available at PhotoNext, one of the 11 new Inter-Departmental Centers at POLITO (www.photonext.polito.it). As required by its mission, PhotoNext will propose a new type of didactical experiences to the PhD students that will follow this course, which will involve three practical “hands-on” laboratory experiments. The three experiences that will be carried out during the course will be on:
- A direct-detection optical fiber transmission systems emulating a fiber to the home (FTTH) access network at 10+ Gbit/s data rate
- A coherent detection optical fiber transmission systems emulating a long-haul fiber network at 100+ Gbit/s
- An overview of the fiber fabrication process, followed by the characterization of an optical fiber in terms of optical attenuation and optical gain.
PERIOD: JUNE - JULY

For each experimental experience, a 3-hour theoretical introduction will be given to allow all students, even if they have heterogeneous backgrounds, to understand the experiments.
For each experimental experience, a 3-hour theoretical introduction will be given to allow all students, even if they have heterogeneous backgrounds, to understand the experiments.
The students will be guided through three different sets of experiments involving optical fiber systems. The experiments will be carried out in PhotoNext, one of the 11 new Inter-Departmental Centers at POLITO (www.photonext.polito.it).
For each of the three experimental experiences, there will be a theoretical introduction (about 3 hours in class) then 3 hours in the laboratory where, together with a research assistant, the experimental setup will first be assembled, then the actual measurements will be taken. Finally, for the following 3 hours, the student will be assisted in post-processing and interpreting the experimental results.
For the first two experiments, a realistic optical fiber transmission systems will be assembled (laser, external modulator, fiber, different type of receivers, optionally optical filters and amplifiers), then the students will have to program a very high speed Arbitrary Waveform Generator to generate the transmitted signal, and to acquire the received signal using a Real Time Oscilloscope. The acquired sample data will then have to be post-processed. The software tool of choice to generate and post-process the experimental data will be Matlab.
For the last experiment, a rare earth doped optical fiber fabricated in our laboratories will be characterized in terms of optical attenuation and optical gain. The students will be given the raw data and will be asked to calculate the loss at 1300 nm, plot the optical gain curve, the laser linewidth, power threshold and slope efficiency.
At the end of the course, in order to pass the exam, each student will have write a report on the results of his/her experiments.
