About

Henrique M. Salgado graduated in Applied Physics (Optics and Electronics) from the University of Porto in 1985 and received the PhD degree in Electronic Engineering and Computer Systems from University of Wales in 1993. He joined the Department of Electrical Engineering and Computers of the University of Porto in 1999 as an Invited Assistant Professor and in 2003 he became Associate Professor. Since 1995 that he heads the Optical and Electronics Area of INESC TEC, begin responsible for several national and internationally funded (EU) research projects. From 1997-1999 he was Research Fellow at the Department of Electrical and Electronic Engineering of the University College London, UK and previously Research Assistant at the School of Electronic Engineering and Computer Systems, Bangor, UK. He is the author and co-author of numerous international publications in the field of optical fibre communications and microwaves. His current research interests include: radio-over-fiber technology and microwave photonics, digital equalization in coherent optical systems, all-optical networks, modeling of nonlinearities and design of compact multiband antennas. He is a member of the Photonics and Communications societies of the IEEE.

Experimental Evaluation of Resonant Tunnelling Diode Oscillators Employing Advanced Modulation Formats

Authors
Tavares, JS; Pessoa, LM; Salgado, HM;

Publication
International Conference on Transparent Optical Networks

Abstract
The performance of Resonant Tunnelling Diode (RTD) oscillators with an optical window is evaluated experimentally, in the transmission of advanced modulation formats using electrical and optical modulation, for the first time. Additionally, the impact of phase noise in the transmission performance is also assessed. © 2018 IEEE.

2017

Analysis of resonant tunnelling diode oscillators under optical modulation

Authors
Tavares, JS; Pessoa, LM; Figueiredo, JML; Salgado, HM;

Publication
International Conference on Transparent Optical Networks

Abstract
In this paper, we investigate the optical modulation characteristics of a resonant tunnelling diode (RTD) oscillator. This preliminary work on the first RTD-PD oscillators with an optical window available from the iBROW project demonstrate that this device can effectively be used to accomplish amplitude and frequency modulation with light injection. © 2017 IEEE.

Nonlinear Compensation Assessment in Few-Mode Fibers via Phase-Conjugated Twin Waves

Authors
Tavares, JS; Pessoa, LM; Salgado, HM;

Publication
JOURNAL OF LIGHTWAVE TECHNOLOGY

Abstract
In this paper, we further explore the concept of phase-conjugated twin waves (PCTW) for nonlinear cancellation in space-division multiplexed (SDM) systems. Previously, we demonstrated that the PCTW technique can successfully provide nonlinear cancellation in SDM systems. In this paper, we investigate the cases where two and four spatial modes are copropagating in a multimode fiber, considering three link lengths (1000, 3200, and 8000 km). Weak-and strong-coupling regimes are also evaluated. Our numerical simulation results show an average performance improvement > 10 dB after a 1000 km transmission link.
