This paper presents two architectures for Radio-Over-Fibre (RoF) Access networks with Peer-to-Peer (P2P) capabilities. The architectures fully exploit the flexibility of a wavelength router based on the feedback configuration of an Arrayed Waveguide Grating (AWG) and an optical switch to enable P2P sessions and dynamic channel allocation of converged wired… (More)
Venue ECoC 2015 will be held in the Feria Valencia Convention and Exhibition Centre (CCE). The CEE is a 7.4 km drive (11 minutes approx.) from Manises Airport and is connected to Valencia downtown by underground lines 1 and 4 and by bus line 62. Valencia is connected daily with Madrid via high-speed train line in less than 1 hr 40 mins each way, and with… (More)
A technique to perform all optical microwave up-conversion is proposed for a RoF system based on the employment of an optical broadband source. The Mach-Zehnder interferometer is the fundamental device for rejecting undesired frequency components.
The authors present a review on the recent approaches proposed to implement transversal RF filters. Different tunable transversal filters consisting of wavelength tunable optical taps and those employing the tunability of dispersive devices are presented showing their high-performance characteristics. A comprehensive review of the fundamentals and a… (More)
Microwave Photonics, a symbiotic field of research that brings together the worlds of optics and radio frequency is currently facing several challenges in its transition from a niche to a truly widespread technology essential to support the ever-increasing values for speed, bandwidth, processing capability and dynamic range that will be required in next… (More)
In this paper, we propose and experimentally demonstrate a novel technique to generate ultrawideband (UWB) doublet pulses by exploiting the cross-phase modulation (XPM) in a semiconductor optical amplifier (SOA). The key component in the proposed system consists on an integrated SOA Mach-Zehnder interferometer (MZI) pumped with a Gaussian pulse modulated… (More)
In this paper, the evolution and current status of generic photonic integration model, from a fabless user perspective, is reviewed. The manufacturers and technologies are described, alongside with photonic chips created by the authors following this model.
To analyze the costs of any optical fiber installation, it is critical to know the evolution of prices of its individual components in time. In this paper we present reliable data prices for several fiber components and we propose future cost trends for them. We extract that, while optical fiber cable manufacturing is a mature technology and no large cost… (More)
In this paper, a novel transmission configuration for SCM/WDM radio over fibre communication systems is proposed and experimentally demonstrated. The scheme is based on the spectrum slicing of a low-cost optical broadband source to obtain a set of optical channels compatible with WDM technology. In order to increase the frequency operation range limited to… (More)
An optical true time delay line (OTTDL) is a basic photonic building block that enables many microwave photonic and optical processing operations. The conventional design for an integrated OTTDL that is based on spatial diversity uses a length-variable waveguide array to create the optical time delays, which can introduce complexities in the integrated… (More)
