Deterministic Timing Jitter Analysis of SOA-Amplified Intensity-Modulated Optical Pulses

Timing of high-intensity pulses for myocardial cavitation-enabled therapy

BACKGROUND High-intensity ultrasound pulses intermittently triggered from an ECG signal can interact with circulating contrast agent microbubbles to produce myocardial cavitation microlesions of potential therapeutic value. In this study, the timing of therapy pulses relative to the ECG R wave was investigated to identify the optimal time point for tissue reduction therapy with regard to both t...

Timing jitter analysis for optical communication systems using ultrashort solitons and dispersion-decreasing fibers

We use adiabatic perturbation theory to calculate the timing jitter induced by fluctuations in solitons amplitude, frequency and position due to amplifiers noise when ultrashort solitons ( ~ ! ps) are propagated in dispersion-decreasing fibers. The result is applied to a high-speed soliton communication system with amplifiers spacing of 50-100 km. We show that the transition from a regime where...

Bandwidth Efficient Root Nyquist Pulses for Optical Intensity Channels

Indoor diffuse optical intensity channels are bandwidth constrained due to the multiple reflected paths between the transmitter and the receiver which cause considerable inter-symbol interference (ISI). The transmitted signal amplitude is inherently non-negative, being a light intensity signal. All optical intensity root Nyquist pulses are timelimited to a single symbol interval which eliminate...

Modeling Timing Jitter in Oscillators

Timing jitter in oscillators is a key factor determining the phase noise performance of phase-locked loops. This paper reviews a theory of phase noise in oscillators, and presents timing jitter models suitable for discrete event simulation of these systems.
