Since 2000, we have developed a unique fiber grating fabrication system. The system allows the inscription of high-quality Fiber Bragg Gratings (FBGs), Long Period Gratings (LPGs) or any other perturbation in many different types of fibres: SMF, MMF, FMF, MCF and PCF amongst others. This fact has allowed us to design and fabricate customized devices for communications, sensors and metrology applications.
Besides, the PRL members have the knowledge of Microwave Photonics which provides us with the skills to develop novel interrogation schemes for optical sensors and metrology.
During the last decades, we have been involved in European and National research projects for the development of advanced communication devices and optical fiber sensors for civil engineering and space applications.
Nowadays, we are participating in the ITN Marie Skłodowska-Curie FINESSE (FIbre NErvous Sensing SystEms) to develop a new generation of distributed optical fiber sensors for a safer society http://itn-finesse.eu/. Also, we are developing new fiber devices in special fibers to improve optical communications [1], advanced metrology [2] and multiparameter/multidimensional fibre sensors [3]-[5].
