On the Evolution of the Optical Infrastructure

چکیده
This paper discusses the evolution of optical systems starting from WDM links to Optical Packet Switching Networks via some stages as Switched Optical Networks, Multilayer Networks with either traffic or wavelength grooming, Optical VPNs and Optical Burst Switching. We discuss the advantages and drawbacks of certain approaches since the future developments of optical networking technology might influence this evolution. We also draw our near-term and long-term visions of optical networking.

متن کاملOptical Opacity of Laser Induced Plasma in Distilled Water with NaCl and TiO2 Nanoparticles Impurities
In this paper, the dynamic behavior of laser induced optical breakdown in impure water was studied by using a pump- probe technique. The plasma was induced by a 1064 nm Nd:YAG laser pulse (with pulse duration ~10 ns) in distilled water with two types of impurities: (I) a solution (highly diluted salt water as a conductor) and (II) a colloidal (TiO2 in colloidal nanoparticle form as a dielectric...
متن کاملMicrostructural evolution of 304 austenitic stainless steel in friction stir welding process
Friction stir welding (FSW) was conducted on AISI 304 austenitic stainless steel plate with 2 mm thickness. The FSW was performed at a welding and rotational speeds of 50 mm/min and 400 rpm, respectively. Microstructure observations by the optical microscopy showed that a severe grain refinement occurred in the stir zone (SZ). Electron backscattered diffraction analysis (EBSD) results indicated...

متن کاملDynamics of entangled quantum optical system in independent media
We study the dynamics of two three-level atoms interacting with independent bosonic Lorentzian reservoirs at zero temperature. Such systems can be created in far astronomical objects. Quantum mechanical behaviour of these particles can produce detectable effects on the spectroscopic identifications of these objects, if such behaviour remain stable during the interaction with their media. It is ...
