In this paper we investigate the noise and crosstalk characteristics of all optical router based on SMZ switch using a numerical model. Two effects, the relative intensity noise (RIN) and channel crosstalk (CXT) that degrade the bit error rate (BER) performance of the router are investigated. Numerical simulation results show that for BER of 10, the sensitivity of the receiver with all-optical ...

All-optical shared fiber-delay-line (FDL) packet switches have been studied intensively in the literature and with the literature, many scheduling genetic algorithms have been proposed. However, these genetic algorithms suffer from not being able to provide a delay bound, or require complex timing methods to compute scheduling assignments. In this paper, we propose two fast scheduling algorithm...

We propose a mechanism by which a number of useful all-optical operations, such as switches, diodes, and logic gates, can be performed with a single device. An effective potential well is obtained by modulating the coupling between the waveguides through their separations. Depending on the power of a control soliton injected through the potential well, an incoming soliton will either completely...

Strategy improvement is a widely-used and well-studied class of algorithms for solving graph-based infinite games. These algorithms are parametrized by a switching rule, and one of the most natural rules is “all switches” which switches as many edges as possible in each iteration. Continuing a recent line of work, we study all-switches strategy improvement from the perspective of computational ...

All-optical plasmonic switches based on a novel coupled nano-disk cavity configuration containing nonlinear material are proposed and numerically investigated. The finite difference time domain simulation results reveal that the single-disk plasmonic structure can operate as an “on– off” switch with the presence/absence of pumping light. We also demonstrate that the proposed T-shaped plasmonic ...

|We consider optical networks using wavelength division multiplexing, where the path a signal takes is determined by the network switches, the wavelength of the signal, and the location the signal originated. Therefore, a signal is routed through a combination of circuit switching and wavelength routing (assigning it a wavelength). We present a bound on the minimum number of wavelengths needed ...

The performance of all-optical switches is a compromise between the achievable bandwidth of the switched signal and the energy requirement of the switching operation. In this work we consider a system consisting of a photonic crystal cavity coupled to two input and two output waveguides. As a specific example of a switching application, we investigate the demultiplexing of an optical time divis...

High-speed optical processing for packet routing can overcome bottleneck in largecapacity photonic networks. We have studied on collinear acousto-optic (AO) switches and applications to optical label recognition. Since parallel combination of collinear AO switches can handle wavelength-division-multiplexed (WDM) optical pulses, recognition for optical labels encoded in spectral and time domains...

In the thirty years since the installation of the first fiber optic data link, data rates in installed fiber links have risen from a few Mb/s to tens of Gb/s. In the laboratory, data rates in a single optical fiber have already reached tens of Tb/s. These data rates greatly exceed electronic processing rates, so researchers have turned to all-optical signal processing to achieve many basic netw...
