Combined single-mode/multimode fiber link supporting simplified in-building 60-GHz gigabit wireless access

Pham, Tien-Thang; Lebedev, Alexander; Beltrán, Marta; Yu, Xianbin; Llorente Sáez, Roberto; Monroy, Idelfonso Tafur (Elsevier, 2012-07)

In this paper, we propose and experimentally demonstrate a simple, cost-effective hybrid gigabit fiber-wireless system for in-building wireless access. Simplicity and cost-effectiveness are achieved in all parts of the ...
EAM-SOA millimeter-wave frequency up-converter for radio-over-fiber applications

Palací López, Jesús; Villanueva Ibáñez, Guillermo Eduardo; Herrera, J. (Elsevier, 2011-01-01)

[EN] We present an optical scheme for photonic frequency up-conversion at the millimeter-wave bands based on Semiconductor Optical Amplifier. The proposed scheme modulates the bias current with the Intermediate Frequency ...
Experimental analysis of 60-GHz VCSEL and ECL photonic generation and transmission of impulse-radio Ultra-Wideband signals

Beltrán Ramírez, Marta; Jensen, Jesper Bevensee; Llorente Sáez, Roberto; Monroy, Idelfonso Tafur (Institute of Electrical and Electronics Engineers (IEEE), 2011-08-01)

[EN] Optical generation of impulse-radio ultra-wideband (UWB) signals in the 60-GHz band is proposed and experimentally demonstrated. External-cavity laser (ECL) and vertical-cavity surface-emitting laser (VCSEL) is employed ...
Novel photonic analog-to-digital converter architecture for precise localization of ultra-wide band radio transmitters

Llorente, Roberto; Morant, Maria; Amiot, Nicolas; Uguen, Bernard (Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)

[EN] A novel photonic analog-to-digital converter (ADC) architecture tailored for the localization of transmitters employing ultra-wide band (UWB) radio technology is proposed and experimentally demonstrated in this paper. ...
