    High-efficiency grating coupler for an ultralow-loss Si3N4-based platform 
    Chmielak, B.; Suckow, S.; Parra Gómez, Jorge; Duarte, V. C.; Mengual Chulia, Teresa; Piqueras Ruipérez, Miguel Ángel; Giesecke, A. L.; Lemme, M. C.; Sanchis Kilders, Pablo (The Optical Society, 2022-05-15)
    [EN] Integrated silicon nitride waveguides of 100¿nm height can achieve ultralow propagation losses below 0.1¿dB/cm at the 1550¿nm wavelength band but lack the scattering strength to form efficient grating couplers. An ...

    Optical fiber-to-chip assembly process for ultra-low loss photonic devices based on silicon nitride for space applications 
    Brimont, Antoine Christian Jacques; Zurita Herranz, David; Duarte, V. C.; Mengual, T.; Chmielak, B.; Suckow, S.; Giesecke, A.; PIQUERAS RUIPÉREZ, MIGUEL ÁNGEL; Sanchis Kilders, Pablo (2020-06-24)
    [EN] In this work, we demonstrate an efficient fiber array-to-chip assembly process with a high number of input/output ports. The proposed approach is based on using a pre-alignment coupling structure to separately align the ...

    Photonic Vector Processing Techniques for Radiofrequency Signals 
    Piqueras Ruipérez, Miguel Ángel (Universitat Politècnica de València, 2016-05-02)
    [EN] The processing of radiofrequency signals using photonics means is a discipline that appeared almost at the same time as the laser and the optical fibre. Photonics offers the capability of managing broadband radiofrequency ...

    Testing Optomechanical Microwave Oscillators for SATCOM Application 
    Mercadé, Laura; Rico, Eloy; Ruiz-Garnica, Jesús; Gómez, Juan Carlos; Griol Barres, Amadeu; Piqueras, Miguel A.; Martínez, Alejandro; Duarte, Vanessa C. (Institute of Electrical and Electronics Engineers, 2022-04-08)
    [EN] The realization of photonic microwave oscillators using optomechanical cavities has recently become a reality. By pumping the cavity with a blue-detuned laser, the so-called phonon lasing regime - in which a mechanical ...
