“…Here, SPM introduces a time-to-frequency mapping, in which different temporal sections of the input pulses acquire different frequency shifts. This process is somewhat analogous to frequency-to-time mapping-based techniques [11]- [13], in which dispersion is used to assign a different delay to different spectral components of an input waveform. The subtraction of the intensity profile of delayed replicas from the original pulse shape might be viewed as a tapped-delay line filtering method.…”

“…High-order waveforms were recently generated using these methods, however their frequency range is restricted by relaxation oscillations to the order of 10 GHz. The most elaborate waveform 0733-8724/$26.00 © 2010 IEEE tailoring was provided by optical spectrum shaping and subsequent frequency-to-time mapping [11]- [13]. These techniques required mode-locked laser sources, and either bulky free-space optics [12] or highly complex fiber gratings with limited tuning [13].…”

Abstract-The generation of ultra-wideband (UWB), high-frequency waveforms based on nonlinear propagation of pulses in optical fibers is reported. Self-phase modulation and subsequent optical filtering are used to implement all-optical edge detectors, which generate two temporally-narrowed replicas of each input pulse. The shapes of the narrowed pulses are subtracted from that of the original one in a balanced differential detector, providing a UWB waveform. The use of multiple replicas and nonlinear propagation allows for the generation of higher-order pulse shapes, beyond those of a Gaussian monocycle or doublet. The output pulse shape is reconfigurable through adjusting the input power and detuning the optical filters. The central radio-frequency of the generated waveforms is as high as 34 GHz, with a fractional bandwidth of 70%.

“…Our approach requires a new FBG if the UWB pulse is to be modified. A programmable version of our pulse generation allows tuning to one of three pulses (monocycle, doublet, or FCC compliant) [14]. The setup described in this paper is modified to exploit two FBG filters with overlapping spectra instead of a single pulse-shaping FBG.…”

This article describes a photonic scheme that performs frequency up‐conversion of baseband pulses for potential applications on Impulse Radio‐Ultra Wideband systems. Mixing a laser modulated by a pulse with a wavelength‐tunable laser (local oscillator) and a coherent photodetection scheme we obtain high order pulses comparable with nth derivatives of a Gaussian pulse. With our approach is possible to perform the frequency translation of the baseband pulses so that UWB pulses within standardized UWB mask are obtained. Baseband components produced in the optical mixing are removed by using a balanced photodetection stage. Our scheme exploits two different microwave photonics technics (microwave generation and coherent detection) for accomplish a simple generator of high order pulses avoiding the use of complex schemes. Additionally, the scheme can be implemented with commercially available components and it is reconfigurable in a very simple way. The performance of the proposed scheme is analyzed and evaluated in this work.© 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2749–2755, 2016
