    An Interrogation Technique of FBG Cascade Sensors Using Wavelength to Radio-Frequency Delay Mapping 
    Hervás Peralta, Javier; Fernandez-Pousa, C.R.; Barrera Vilar, David; Pastor Abellán, Daniel; Sales Maicas, Salvador; Capmany Francoy, José (Institute of Electrical and Electronics Engineers (IEEE), 2015-06-01)
    A technique is proposed to interrogate a distributed photonic sensor composed of seven standard fiber Bragg gratings in cascade. A microwave-modulated optical signal is launched into an FBG cascade and subsequently ...

    Coherency-Broken Bragg Filters: Overcoming On-Chip Rejection Limitations 
    Oser, Dorian; Mazeas, Florent; Le Roux, Xavier; Pérez-Galacho, Diego; Alibart, Olivier; Tanzilli, Sébastien; Labonté, Laurent; Marris-Morini, Delphine; Vivien, Laurent; Cassan, Éric; Alonso-Ramos, Carlos (John Wiley & Sons, 2019-08)
    [EN] Selective optical filters with high rejection levels are of fundamental importance for a wide range of advanced photonic circuits. However, the implementation of high-rejection on-chip optical filters is seriously ...

    Phase and Amplitude Stability of EHF-Band Radar Carriers Generated From an Active Mode-Locked Laser 
    Serafino, Giovanni; Ghelfi, Paolo; Pérez Millán, Pedro; Villanueva Ibáñez, Guillermo Eduardo; Palací López, Jesús; Cruz, Jose Luis; Bogoni, Antonella (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    [EN] We study the phase and amplitude stability of RF signals, generated at different frequencies by heterodyning pairs of modes from the optical spectrum of an active mode-locked laser, and we focus on the dependence of ...
