Fiber lasers mode-locked with normal cavity dispersion have recently attracted great attention due to large output pulse energy and femtosecond pulse duration. Here we accurately characterized the timing jitter of normal-dispersion fiber lasers using a balanced cross-correlation method. The timing jitter characterization experiments show that the timing jitter of normal-dispersion mode-locked f...

The advent of modern-day wireless communications systems as well as other high speed applications imposes exceedingly challenging demands on state-of-the-art Analog-to-Digital Converters (ADCs). The evolution of receiver architectures necessitates very high Signal-to-Noise Ratio (SNR) at intermediate frequencies that up until recently were impossible to achieve. Recent breakthroughs in converte...

Period Jitter Period jitter (JPER) is the time difference between a measured cycle period and the ideal cycle period. Due to its random nature, this jitter can be measured peak-to-peak or by Root of Mean Square (RMS). We begin by defining the clock rising-edge crossing point at the threshold VTH as TPER(n), where n is the time domain index, as shown in Figure 1. Mathematically, we can describe ...

Key performance specifications Up to 1.6 Gb/s Pattern Generator/Error detector for fast, accurate characterization of digital communications signaling systems PRBS or 8 Mb user-defined patterns provide the versatility to debug or verify any combination of digital signaling ANSI jitter measurements (RJ, DJ, and TJ) to measure the impact of random and deterministic jitter on the total jitter at B...

We investigate both experimentally and theoretically the behavior of pulse jitter in compact disk (CD) self-pulsating lasers that have been synchronized to an applied periodic electrical signal. Our investigations reveal that pulse-to-pulse jitter in a synchronized laser is almost entirely unchanged from that in an unsynchronized laser under the same bias conditions. The major effect of synchro...

In this paper we study the effect that jitter and phase noise have on the precision of amplitude estimation of the harmonics of a periodic signal. The analysis carried out is applicable to both Three-Parameter Sine Fitting as well as Coherent Discrete Fourier Transform procedures. We consider the case where jitter and phase noise on the signal or sampling clock is small when compared with the s...

This paper focuses on the effect on BER, Q-Factor for a four user OCDMA communication system with varying Jitter. Performance of the OCDMA communication system has been evaluated in terms of bit error rate and Q factor with jitter varying from 0 pico-seconds to 3.0 picoseconds in steps of 0.5 pico-seconds. Simulations were carried out using commercially available simulator from Rsoft, OPTSIM. K...
