Optical Burst Switching

Optical burst switching is a promising solution for all optical WDM networks It combines the benefits of optical packet switching and wavelength routing while taking into account the limitations of current all optical technology In OBS the user data is collected at the edge of the network, sorted based on destination address,and grouped into variable sized bursts Prior to transmitting a burst, a control packet is created and immediately send toward the destination in order to setup a buffer less ....etc

MICROELECTROMECHANICAL SYSTEMS



WHAT IS MEMS?
Submicron manufacturing promises to
provide economic solutions to meeting
increasingly demanding customer needs and, at the same time, decreasing time to market,energy consumption, and environmental costs. Manufacturing at the submicron level has four evolutionary advances in (1) miniaturization and (2) microelectromechanical systems (MEMS), as well as revolutionary advances in (3) nanofabrication and (4) biotechnology. This paper deals with MEMS.

ABSTRACT
Optical packet switching promises to bring the flexibility and efficiency of Internet to transparent optical networking with bit rate extending beyond that currently available with electronic router technologies. New optical signal processing have been demonstrated that enable routing at bit rates from 10gb/s to beyond 40gb/s.in this article we review these signal processing techniques and how all optical wavelength converters technology can be used to implement packet switching functions. Specific approaches that ....etc

Introduction:
Microelectromechanical systems (MEMS) (also written as micro-electro-mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems) is the technology of very small mechanical devices driven by electricity; it merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are also referred to as micromachines (in Japan), or Micro Systems Technology - MST (in Europe).
MEMS are separate and distinct from the hypotheti ....etc

OPTICAL devices

INTRODUCTION
Explosive information demand in the internet world is creating enormous needs for capacity expansion in next generation telecommunication networks. It is expected that the data- oriented network traffic will double every year. Optical networks are widely regarded as the ultimate solution to the bandwidth needs of future communication systems. Optical fiber links deployed between nodes are capable to carry terabits of information but the electronic switching at the nodes limit th ....etc

ABSTRACT
Theoretically optical switches seem to be future proof with features of scalability, flexibility, bit rate and protocol independent coupled with lower infrastructure costs but a network service provider must evaluate the pros and cons and all possible options to select optimum combination of electronic and photonic switches to meet the capacity and traffic management requirements. This seminar presents an overview on optical switches.
Optical switches including mems, bubble, Thermo-optical, Liquid crystal and n ....etc
