Performance of a 60-GHz DCM-OFDM and BPSK-Impulse ultra-wideband system with radio-over-fiber and wireless transmission employing a directly-modulated VCSEL

Beltrán, Marta; Jensen, Jesper Bevensee; Yu, Xianbin; Llorente, Roberto; Rodes, Roberto; Ortsiefer, Markus; Neumeyr, Christian; Monroy, Idelfonso Tafur (Institute of Electrical and Electronics Engineers (IEEE), 2011-06-06)

[EN] The performance of radio-over-fiber optical transmission employing vertical-cavity surface-emitting lasers (VCSELs), and further wireless transmission, of the two major ultra-wideband (UWB) implementations is reported ...
Spectral self-imaging effect by time-domain multilevel phase modulation of a periodic pulse train

Caraquitena Sales, José; Beltrán, Marta; Llorente, Roberto; Martí Sendra, Javier; Muriel, Miguel A. (Optical Society of America, 2011)

[EN] We propose and analyze a novel (to our knowledge) approach to implement the spectral self-imaging effect of optical frequency combs. The technique is based on time-domain multilevel phase-only modulation of a periodic ...
