Nanoparticles-doped optical fiber is a new class of optical fibers developed to promote improved fiber lasers, amplifiers and sensors. Rare-earth (RE) doped optical fibers are extensively used in lasers and optical amplifier devices. These key applications rely on the qualities of silica glass: mechanical and chemical stability, high optical damage threshold, low cost, etc. However, silica glass has certain characteristics which may make it less efficient compared to other types of glass, particularly in some potential applications using RE ions: high phonon energy, low solubility of RE ions, etc.To overcome these limitations, one recent strategy consists of developing a fabrication method which triggers REencapsulation in phase-separated nanoparticles. Nanoparticles induce light scattering which is an issue for fiber lasers and amplifiers. However, it is also a great opportunity for new applications. For instance, such fibers can be used for illumination (light diffusing fiber). Very recently, temperature, strain, refractive index and 3D shape sensors have been reported based on highly scattering fibers and exploiting the optical backscatter reflectometry. During this course, we will discuss on the fabrication processes of nanoparticles-doped optical fibers. Different techniques used to characterize such fibers will be presented. As nanoparticles in optical fibers can be amorphous, specific high resolution measurements of the composition (Secondary Ion Mass Spectrometry, Atom ProbeTomography) will be introduced. Finally, different applications will be reviewed, emphasizing nanoparticles-doped fiber sensors.

Radar Systems Overview: From Microwave To Quantum Radar

Radar systems have known impressive advances throughout their long history, pushing electronics to progress. The lack of electronic systems capable of directly generating, processing and digitizing signals that have high central frequencies and large bandwidths directed the attention to optical field. Radar systems based on the quantum measurement are not only able to perform conventional target detection and recognition but also able to reach the detection of RF stealth platform and weapons systems. Any attempt to deceive quantum radar will be revealed due to the strong correlation between entangled photons. This short course will cover key aspects of different radar technologies, from microwave to quantum radars, providing the student an overview of the basic theory and principles relating to RADAR. It will be presented some current applications and state of the art technologies. Recently, the precision of the traditional radar has been improved by exploit technologies like synthetic aperture technique (SAR), phased array technology, multi-band joint detection and various data processing algorithms. Classical methods have been applied to its extreme in order to increase performance of radar systems, but still it is unable to break through the standard quantum limits.

Technology and digitalization have caused a global metamorphosis both in people’s professional and personal life and staying connected and tuned has become a day-to-day concern. This is also causing a significant impact on the industrial and overall business environment. The rising need for asset management have occupied a critical role on every company agenda. This together with the optimization of the operations and cost reduction have caused a growing importance of the remote monitoring and diagnostics topic within this new industrial revolution era, the well-known Industry 4.0. Remote Monitoring and Diagnostics RM&D is a topic that puts together sensing and IoT, communications such as radio, satellite or cellular, cloud systems, data analytics and machine learning modelling in a single and integrated solution. However, in order to properly manage and implement these programs, there are many considerations that take place. For instance, reducing downtime on the industrial environment will require high speed communication infrastructures and accurate and dependable access to remote data; and its expedit processing too. This combination of sensors with reliable and safe communication and data analytics will be capital to faster response to faults, and events to be correctly diagnosed and preventive maintenance to be performed in more efficient ways. This scenario together with the highly competitive Industry 4.0 environment will create challenges that can bring numerous opportunities for academic research as well as innovation to industrial processes.

Digital Signal Processing Techniques for Coherent Optical Transmission Systems (OptDSP)

Fernando Pedro Pereira Guiomar

Instituto de Telecomunicações, Aveiro – Portugal.


The OptDSP short course will address the most fundamental aspects of modern coherent optical communications, from IQ signal modulation to coherent detection and forward error-correction. After a generic overview of coherent optical communications, basic and advanced modulation concepts will be discussed, together with the most appropriate performance metrics depending on the characteristics of the coherent transceiver. Special attention will be given to the compensation of transmission impairments that are specific to optical fiber transmission, such as laser phase noise and nonlinear distortions. Finally, more advanced concepts of multi-carrier modulation through subcarrier multiplexing will be presented and discussed. Each topic of the short course will be initially introduced through presentation slides and then explored in detail using MATLAB-based live scripts. Both media formats will be made available to the audience for a more interactive experience.
