The demonstration of an all-optical shift register is introduced by using master-slave integrated configuration of Self Electro-optic Effect Devices. The system structure, system performance and some possible improvements are presented. The dependence of the switching performance is discussed by analyzing device transmission coefficients and absorption coefficients. Based on these performance a...

The main theoretical and experimental backgrounds of two-photon absorption (TPA) and TPA-induced free carriers in silicon are presented in detail. In particular, the mostly recent experimental achievements in applications of TPA and TPAinduced free carriers are discussed, such as optical limiting, optical pulse shaping, all-optical switching and modulation, alloptical logic gates, all-optical w...

We report on the achieving of Bose-Einstein condensation of a dilute atomic gas based on trapping atoms in tightly confining CO2-laser dipole potentials. Quantum degeneracy of rubidium atoms is reached by direct evaporative cooling in both crossed and single beam trapping geometries. At the heart of these alloptical condensation experiments is the ability to obtain high initial atomic densities...

One promising approach for scalable quantum computing is to use an alloptical architecture, in which the qubits are represented by photons and manipulated by mirrors and beam splitters. So far, researchers have demonstrated this method, called Linear Optical Quantum Computing, on a very small scale by performing operations using just a few photons. In an attempt to scale up this method to large...

The high-index contrast between the silicon core and silica cladding enable low cost chip-scale demonstration of alloptical nonlinear functional devices at relatively low pump powers due to strong optical confinement the in silicon waveguides. So far, broad ranges of applications from Raman lasers to wavelength converters have been presented. This presentation will highlight the recent developm...

Two properties of optical transmissions, namely, unidirectional propagation and predictable propagation delay, make it possible to pipeline packet transmissions in alloptical networks. In this paper, we study the problem of scheduling All-to-All Personalized Communication (AAPC) in unidirectional TDM/WDM rings with pipelined transmissions, which can achieve a much higher bandwidth utilization t...

The tradeoffs involving the use of multi-fiber multihop networks such as the number of fibers, number of wavelengths, conversion options, and the different switch configurations are examined, and their impact on end-to-end blocking and throughput performance is evaluated. Models relating network parameters to end-to-end performance of circuit switched alloptical networks are developed. The perf...

Permutation routing is a popular communication pattern in the interconnection networks. Most of the previously proposed routings algorithms on Multistage Interconnection Networks (MINs) work on 2×2 switches. We considered alloptical rearrangeable permutation routing for Clos Interconnection networks. The signal in the optical switch with the same wavelength will cause the crosstalk problem.In t...

This paper presents a novel wavelength assignment algorithm for alloptical networks. The main idea is to determine the wavelength assignment order for a first fit algorithm taking into account the physical layer effects of four wave mixing and residual dispersion by using a training algorithm inspired in evolutionary computation concepts. The intelligent algorithm presents some concepts recentl...

Teknologi TCP end-to-end congestion control hanya menangani kemacetan jaringan dari suatu host tetapi tidak pada atau intermediate network, oleh karena itu teknologi Active Queue Management (AQM) dikembangkan untuk mengantisipasi didalam yaitu router. AQM dapat mengatasi buffer overflow router dan mencegah terjadinya masalah sinkronisasi yang padat, dengan mendeteksi sebelum terjadi jaringan. R...
