A Fully Differential Digital CMOS Pulse UWB Generator [PDF]
, 2009 A new fully-digital CMOS pulse generator for impulse-radio Ultra-Wide-Band (UWB) systems is presented. First, the shape of the pulse which best fits the FCC regulation in the 3.1-5 GHz sub-band of the entire 3.1-10.6 GHz UWB bandwidth is derived and ...

Pulse pedestal suppression using four-wave mixing in an SOA [PDF]
, 2008 Experimental results are presented demonstrating how four-wave mixing in a semiconductor optical amplifier can be used to remove pulse pedestals introduced due to nonlinearities which occur upon pulse propagation in an optical system.

Pulse wave analysis in normal pregnancy: a prospective longitudinal study. [PDF]
, 2009 Outside pregnancy, arterial pulse wave analysis provides valuable information in hypertension and vascular disease. Studies in pregnancy using this technique show that vascular stiffness is raised in women with established pre-eclampsia.

Wavelength and duration tunable 10 GHz 1.3ps pulse source using dispersion decreasing fiber based distributed Raman amplification [PDF]
, 2004 We experimentally demonstrate a novel pulse compression scheme using dispersion decreasing fiber (DDF) based distributed Raman amplification. We adiabatically compress 10GHz, 13ps seed pulses generated using a commercially available electro-absorption ...

All-optical pulse retiming based on quadratic cascading in a periodically poled lithium niobate waveguide [PDF]
, 2010 We demonstrate an all-optical technique for the elimination of timing jitter in short pulse transmission systems. The technique relies on pulse pre-shaping followed by optical switching in a periodically poled lithium niobate waveguide via cascaded ...

Spectral meta-moments reveal hidden signatures of vortex pulses [PDF]
EPJ Web of Conferences, 2019 Ultrashort vortex pulses possess specific spatio-spectral signatures due to Gouy phase shift. Helical movement of anomalies around the phase singularity was found which is referred to as spectral Gouy rotation. The analysis of spectral moments allows for
