Periodical spectral peaking on optical pulses
WebJul 21, 2024 · Here, we discovered a novel phenomenon in ultrafast nonlinear fiber optics, namely, periodical spectral peaking. A narrow spectral dip on a pulse turns into a sharp, … WebFor optical pulses, timing jitter is related to phase noise in the optical frequency components of the pulse train (see below). In the absence of technical noise, the jitter of a mode-locked laser is limited by quantum …

WebJul 20, 2024 · In this paper, we propose a much compact ultrashort optical pulse repetition rate multiplication approach based on two-core-fiber Mach–Zehnder interferometer. Since the temporal period is approximately inverse-proportional to its spectral spacing, the repetition rate of output pulses can be doubled (Multiplication factor N = 2) by selecting … WebThe imposition of a periodic spectral phase function onto a short pulse is known to result in the generation of a burst of op-tical pulses [13]. Approximating the VIPA spectral dispersion within a single diffraction order as linear, we can write (1) as E out(ω)=E in(ω)H(ω) =E in(ω) in which we generate optical pulse bursts and manipulate the k
WebA polynomial fit to the frequency-dependent pulse phase (spectral phase) gives values of 5.6 3 103fs2and 24.0 3 105fs3for the quadratic and cubic dispersion terms, respectively. The … WebSpecifically, 81% suppression is achieved for both pulses, relative to the peak power of the other pulses in the periodic sequence. This value is consistent with the theoretical 83% suppression found in the output train obtained by numerical simulation.
WebJan 1, 2024 · By using interleaving filters and binary receiver array, the spectral information in optical pulses can be directly encoded as digital signals. Compared with the photonic ADC schemes based on MZMs, the proposed scheme uses only one modulator and a single fiber to realize 2 N quantization levels. WebSpectral peaking during supercontinuum generation in normal dispersive highly nonlinear fiber was investigated both numerically and experimentally. Sharp multiple spectral peaks were generated stably with 290 GHz frequency interval, and …
