    Measurement of polarization dependent loss, polarization mode dispersion and group delay of optical components using swept optical single sideband modulated signals
    (Optical Society of America, 2008) Sagüés García, Mikel; Pérez Echegoyen, Miguel; Loayssa Lara, Alayn; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa; Gobierno de Navarra / Nafarroako Gobernua, 13326
    We introduce a novel method for high wavelength-resolution measurement of polarization-averaged group delay, polarization dependent loss and polarization mode dispersion of optical components using swept optical single sideband modulated signals. Measurements of a phase-shifted fiber Bragg grating, a chirped fiber Bragg grating and of the Brillouin spectra of a length of fiber are used in order to demonstrate the technique.

    Distortion-free Brillouin distributed sensor using RF shaping of pump pulses
    (SPIE, 2009-10-05) Zornoza Indart, Ander; Olier Aguado, David; Sagüés García, Mikel; Loayssa Lara, Alayn; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    We demonstrate a novel configuration for Brillouin optical time domain analysis based on single-sideband modulation and RF shaping that provides pump pulses with 80-dB extinction ratio. This extremely reduced leakage, which to our knowledge is the lowest ever achieved, completely suppresses distortion of the measured spectra, thus sensor precision is enhanced. Furthermore, the proposed setup results in a simplified system with only one modulator and no need for optical filtering in detection.

    Multi-tap complex-coefficient incoherent microwave photonic filters based on optical single-sideband modulation and narrow band optical filtering
    (Optical Society of America, 2008) Sagüés García, Mikel; García Olcina, Raimundo; Loayssa Lara, Alayn; Sales, S.; Capmany, José; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    We propose a novel scheme to implement tunable multi-tap complex coefficient filters based on optical single sideband modulation and narrow band optical filtering. A four tap filter is experimentally demonstrated to highlight the enhanced tuning performance provided by complex coefficients. Optical processing is performed by the use of a cascade of four phase-shifted fiber Bragg gratings specifically fabricated for this purpose.
