Space-Division Multiplexing for Microwave Photonics
Despite Space division multiplexing fibers were initially envisioned as pure
transmission media, they exhibit as well great potential for signal processing.
We review here different solutions we developed for microwave signal processing
devices and links.Comment: 2019 24th OptoElectronics and Communications Conference (OECC) and

Development of a dc-ac power conditioner for wind generator by using neural network
This project present of development single phase DC-AC converter for wind
generator application. The mathematical model of the wind generator and Artificial
Neural Network control for DC-AC converter is derived. The controller is designed to
stabilize the output voltage of DC-AC converter. To verify the effectiveness of the
proposal controller, both simulation and experimental are developed. The simulation and
experimental result show that the amplitude of output voltage of the DC-AC converter
can be controlled
Space-division multiplexing for fiber-wireless communications
We envision the application of optical Space-division Multiplexing (SDM) to
the next generation fiber-wireless communications as a firm candidate to
increase the end user capacity and provide adaptive radiofrequency-photonic
interfaces. This approach relies on the concept of fiber-distributed signal
processing, where the SDM fiber provides not only radio access distribution but
also broadband microwave photonics signal processing. In particular, we present
two different SDM fiber technologies: dispersion-engineered heterogeneous
multicore fiber links and multicavity devices built upon the selective
inscription of gratings in homogeneous multicore fibers.Comment: 4 pages, 20th International Conference on Transparent Optical

Fiber-distributed Signal Processing: Where the Space Dimension Comes into Play
[EN] We implement "fiber-distributed signal processing" in the context of fiber-wireless
communications by using different multicore fibers, providing both radio access distribution and microwave photonics signal processing in the same fiber medium.This research was supported by the ERC Consolidator Grant 724663, the Spanish Projects TEC2014-60378-C2-1-R, TEC2015-62520-ERC and TEC2016-80150-R, the Spanish scholarships MECD FPU13/04675 for J.
