“…To overcome EAWG shortcomings, photonic techniques with their well-known advantages such as large operation bandwidth, low loss, and long-distance transmission capability are utilized for optical arbitrary waveform generation (OAWG) [8]. In this way, Fourier transform pulse shaping followed by frequency-to-time mapping [9]- [10] and discrete space-to-time mapping [11]- [12] have already been proposed and demonstrated; still, those approaches have complex systems.…”

A photonics-assisted scheme for generating various microwave waveforms has been investigated in this paper. In the proposed scheme, two phase modulation to intensity modulation (PM-IM) conversions are realized using two cascaded Sagnac interferometers (SIs) to manipulate light in the optical domain. From the first SI, by adjusting the amplitude of the microwave signal and time delay of the tunable optical delay line (TODL), both half duty cycle square and full duty cycle triangular waveforms can be generated from the photodetector (PD) and balanced photodetection (BPD). Using the second SI and applying microwave signals with appropriate amplitudes and phases, as well as the BPD process, results in full duty cycle sawtooth and reversed sawtooth waveforms. Detailed theoretical analyses are presented and results are verified by simulations. In the simulations, square-, triangular-and sawtooth-shaped (or reversed sawtooth-shaped) waveforms are obtained successfully. To complete the simulation results, the effects of non-ideal microwave hybrid coupler and optical couplers on the performances of the proposed scheme have been studied and no destructive effects were observed. The proposed structure does not include any optical or electrical filters which result in a wide operational bandwidth.

“…Among the numerous approaches proposed to date for OAWG 13,14 , the Fourier synthesis method 7 remains the most popular one, and in fact, programmable pulse-shaping devices based on this principle are commercially available. This method is based on user-defined filtering of the amplitude and phase profiles of a broadband phase-coherent optical spectrum, e.g., a short optical pulse from a mode-locked (ML) laser.…”

Controlling the temporal and spectral properties of light is crucial for many applications. Current state-of-the-art techniques for shaping the time- and/or frequency-domain field of an optical waveform are based on amplitude and phase linear spectral filtering of a broadband laser pulse, e.g., using a programmable pulse shaper. A well-known fundamental constraint of these techniques is that they can be hardly scaled to offer a frequency resolution better than a few GHz. Here, we report an approach for user-defined optical field spectral shaping using a simple scheme based on a frequency shifting optical loop. The proposed scheme uses a single monochromatic (CW) laser, standard fiber-optics components and low-frequency electronics. This technique enables efficient synthesis of hundreds of optical spectral components, controlled both in phase and in amplitude, with a reconfigurable spectral resolution from a few MHz to several tens of MHz. The technique is applied to direct generation of arbitrary radio-frequency waveforms with time durations exceeding 100 ns and a detection-limited frequency bandwidth above 25 GHz.

“…Because of bandwidth limitations of electronic arbitrary waveform generation (AWG), photonic techniques have been attracting major attention due to their broadband nature, fiber distribution compatibility, reconfigurability, immunity to EMI, along with smaller size and weight [115]. A different number of fiber-based techniques have been demonstrated for optical AWG, such as frequency-to-time mapping [116], [117], phase-modulation-to-intensity-modulation conversion [118], and microwave signal filtering [119], [120].…”

Para empezar, esta tesis no habría sido posible sin el apoyo recibido por parte de mis directores de tesis, Ivana y Sergi. En particular, a Ivana quisiera agradecerle la oportunidad de formar parte de este grupo de investigación y el poder realizar esta tesis doctoral. A Sergi me es imposible agradecerle completamente toda la ayuda, compañerismo y buenos consejos que me ha prestado a lo largo de todos estos años que hemos estado trabajando juntos.Quiero agradecer también a todos mis compañeros en el PRL (en particular al SDM team) por contribuir a crear un entorno laboral agradable. De forma especial me gustaría agradecer a Rubén, Sergi (otra vez) y Javi por los buenos ratos en los descansos, comidas, actividades y demás momentos.Despite being there for a short time, I would like to thank the people at the Max-Planck Institute in Erlangen for being so kind with me and for their assistance. In particular, I would like to acknowledge Dr. Michael Frosz, Linda Weise and Thomas Stelzer.També vull agrair a tota la meua família el suport que m'han donat tots estos anys. En especial, als meus pares i a la meua germana, per animar-me a estudiar i ajudarme sempre en tot.Por último, quiero agradecer a mis amigos y compañeros de carrera todo el interés y el apoyo recibido todos estos años. Por supuesto, no habría podido superar el largo camino para llegar hasta aquí sin el apoyo de Esther, gracias por compartir conmigo los buenos y los malos momentos.
