Ricardo Oliveira received his PhD in Physics Engineering from the University of Aveiro, Portugal, in September 2017, and his MSc in Biomedical Engineering from the University of Coimbra, Portugal, in 2010. Throughout his career, Ricardo has contributed to 21 research projects focused on fibre optic technologies, particularly in the areas of sensing, devices, and communications.Ricardo is currently a Researcher at the Instituto de Telecomunicações in Aveiro, where he serves as PI and co-Pi of different projects focused on additive manufacturing, multicore fibre applications, polymer optical fibres and sensors.Since 2018, Ricardo has held the position of Invited Professor in Applied Optics at the University of Aveiro's Physics Department. Ricardo has authored over 40 papers in leading international journals and more than 40 papers in international conference proceedings, including five invited contributions. He is also the first author of books and book chapters. His research interests include short- and long-period fibre gratings, fibre optic sensors, optical communications, polymer optical fibres, microstructured fibres, additive manufacturing, fibre post-processing and micro- and nano-scale 3D printing through two-photon polymerisation. Nuno Valente received his MSc degree in Physics Engineering at University of Aveiro, Portugal, in July 2023. He then worked as a researcher in a nationally funded project (FOPE-COMSENS - PTDC/EEI-TEL/1511/2020) at Instituto de Telecomunicações in Aveiro, Portugal. His areas of expertise include fibre optic sensors and components, such as fibre interferometers and fibre grating technology. His expertise extends to the field of freeform additive manufacturing of optical waveguides and components. Currently, Nuno works as a Calculation and Simulation Engineer at Bontaz, conducting simulations in fluid dynamics, electromagnetics, and performing structural analysis using ANSYS software.
