This report documents the JB_PH lattice Boltzmann code, a program for modeling multi-component flow and dispersion. Accuracy of the code is tested with four benchmark problems: (1) permeability of a simple cubic array of spheres; (2) Taylor-Aris dis
The moment method is used to calculate the Ramaninduced timing jitter generated by amplifier-induced fluctuations in the energy, frequency, and position of optical pulses propagating inside dispersion-managed fiber links. Using a Gaussian form for c
This paper illustrates some salient dispersion properties of the Coifman scaling function based MRTD technique (Coifman S-MRTD) and discusses its applicability to modeling problems of interest. Having been recently introduced, this method presents a
An exact theory describing the intensity PSD of photonic signal processors based on modulated thermal sources with smooth spectrum, first-order dispersion and intensity-noise-limited direct detection is presented. The theory is applied to the evaluat
A detailed descr iption of dispersion, including fundamentals of dispersion, dispersion measurement and how to make use of it. It contains lots of graphs about dispersion.
Monitoring network traffic and detecting unwanted applications has become a challenging problem, since many applications obfuscate their traffic using unregistered port numbers or payload encryption. Apart from some notable exceptions, most traffic
Study of PVM/MA nanoparticles in a process of solution-enhanced dispersion by supercritical CO2，陈爱政，王光亚，The supercritical CO2-based technologies have been widely used in the formation of drug and/or polymer particles for biomedical applications. In t
A compact and stable all-normal-dispersion mode-locked ring fiber laser with the repetition rate of 312 MHz is obtained with a wavelength-division multiplexing isolator. The compressed pulse is nearly transform-limited and the pulse width is 118 fs.
There are two different effects to generate group delay dispersion by multilayer thin film mirrors: chirper effect and Gires-Tournois effect. Both effects are employed to introduce desired dispersion in the designed mirror. Thus the designed mirror p
We propose a 1st and 2nd order polarization mode dispersion emulator (PMDE) with one variable differential group delay (DGD) element using birefringence crystals and four polarization controllers (PCs). Monte Carlo simulations demonstrate that the ou
A novel lens system with correction of secondary spectrum without using anomalous glasses is presented. The lens system comprises four separated lens components, with three of them being subapertures. Two examples of apochromatic telescope are presen
We report a broadband polarization-independent wavelength conversion by reducing the dispersion discrepancy between the fundamental transverse electric (TE) and transverse magnetic (TM) modes in a silicon nanowire waveguide, through optimizing of the
We propose a technique for chromatic dispersion monitoring based on optical time domain level monitoring. Experimental and simulation results show that the technique is effective for the monitoring of dispersion in 42.7-Gbps CS-RZ signals for dynamic
We report on the experimental realization of Cerenkov sum-frequency generation across the material dispersion in a one-dimensional, periodically poled ferroelectric crystal. Three schemes of sum-frequency generation, confined only in the vicinity of
