The Photonics Research Labs (PRL) is a scientifical research group of the Institute of Telecommunications and Multimedia Applications (iTEAM) whose field of interest is the photonic technology and its applications to solve the challenges of the industry and society. It is located at the Polytechnic City of Innovation, Scientific Park of the Universitat Politècnica de València (UPV). HistoryThe Photonics Research Labs has its origins in the former Optical and Quantum Communications Group, initially hosted from 1991 to 2005 at the Communications Department. The group is a founding member of the Institute of Telecommunications and Multimedia Applications, which was recognized as University Research Institute by the Valencian Regional Government on July 29th.[1] ResearchNowadays, the PRL is formed by nearly 40 telecom engineers and physicists, including Full Professors, Postdoctoral Researchers and PhD students. The Photonics Research Labs has been involved in more than 100 Spanish and European projects (including two ERC Grants[2][3]), has published over 400 papers in peer reviewed journals and has registered more than 20 patents. PRL has helped to create three start-up companies (spin-offs), who provide design, prototyping and manufacturing of photonic integrated circuits (VLC-Photonics -2011-); design, prototyping and manufacturing of optical fibre sensors for structural health monitoring (CALSENS -2013-) and advanced Instrumentation for Microwave Photonics and Radio over fiber systems (ePHOOX -2016-). The PRL research activity is focused on several applications of photonics, mainly on optical communications of analog and digital signals, radio-over-fiber systems and photonic integrated circuits. Part of the research is also performed in the field of fiber optic sensor and industrial photonics. Microwave PhotonicsThe head of PRL, [https://scholar.google.com/citations?user=vvuEpskAAAAJ&hl=en Professor José Capmany] is considered a world-leading researcher in Microwave Photonics (MWP), principally due to his contributions to the field of microwave photonic signal processing, a fundamental technology for the convergence of fixed and wireless telecommunication networks. In fact, the renowned journal [https://www.nature.com/nphoton/ Nature photonics] published in January 2019 a [https://www.nature.com/articles/s41566-018-0310-5 review paper on Integrated Microwave Photonics] co-written by him in collaboration with Professor Jianping Yao and Professor David Marpaung. PRL research concerning MWP include tunable and reconfigurable microwave filters based in fibre gratings and delay lines for the processing of radiofrequency, microwave and milimetric signals, directly in the optical domain, remote antenna array feeders by means of optical delay lines (beamforming and beam stearing), signal processing and distribution over space-division multiplexing (SDM) optical fibers, Slow and Fast Light (SFL) effects applied to Microwave Photonics, implementation of tunable broadband microwave phase shifting and true time delay functionalities by means of different SFL technologies as Coherent Population Oscillations in Semiconductor Optical Amplifiers and stimulated Brillouin scattering in optical fibers, RADAR and Ultra Wide Band (UWB) applications and Optical Frequency Division Multiplexing (OFDM) techniques. Photonic integrated circuitsDesign of integrated photonic devices for multiple applications (optical telecom, optical signal processing, sensing, biophotonics): Silica or PLC (SiO2), Silicon-on-Insulator (SOI), Silicon Nitride (Si3N4), active devices in InP. Cryptography and quantum informationThe research line is focused on the applications of Quantum Mechanic principles to information processing in optical telecommunication systems (Entanglement, Quantum state teleportation and Encryption). Fibre Bragg Gratingsdesign and fabrication of Fibre Bragg Gratings for communication networks (Dispersion compensation and optical filters) and Sensing applications (high temperature, stress, pressure, chemical). Optical NetworksOptical links conform a large part of the current global communication network, and the trend is growing with the latest. deployments of Fiber-to-the-Home, (FTTH) networks and fiber backhauling of mobile and radio networks. With this background, PRL develops it's research in the following lines: Architectures in optical path switching networks, Architectures in optical packets switching networks, Photonic systems based on code division multiplexing for access networks and Reconfiguration in access and in-building networks, Optical processing of signals in Broadband Networks and Access Networks. Also, Advanced modulation formats, such as OFDM in optical networks, are being deeply theoretically and experimentally explored in different configurations in order to optimize the design paremeters to maximize the networks performance. OFDM-based Optical Communications SystemsThe use of the OFDM modulation in optical communication has attracted a high interest in recent years thanks to the possibility of simple equalization with moderate implementation complexity using digital signal processing techniques. The objectives of this research line are: development of algorithms for direct detection optical OFDM, analysis and evaluation of nonlinear optical effects in optical OFDM, implementation of a real-time demonstrator using high speed data converters (Gbps). StructureThe group is structured in different Research Labs that focus in different related technologies with different fields of applications.
