Ever-increasing customer demand for new broadband applications requires the implementation of smarter strategies for routing and information exchange among networks.

Bottleneck at nodes interconnecting Metro and Access networks can be resolved by using more intelligent algorithms. “Minimal Deflection” or “Scale Routing”.

New approaches to tackling this problem have recently been investigated by various groups, making this one of the new “hot”topics in the community.

Interconnection of Metro and Access networks, developing and applying algorithms for integrating both levels and looking for ways to improve the routing and information exchange among networks.

Resource optimization with the application of new strategies that consider the information exchange mentioned above.

Introduction

Today, the pure science of optics is called optical science or optical physics to distinguish it from applied optical sciences, which are referred to as optical engineering. Subfields: illumination engineering, photonics, and optoelectronics. Applications: physics, medicine, engineering,

photography, industry, recreation

Introduction

Optics: branch of physics which studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.*

* Wikipedia. The Free Encyclopedia

Photonics: This science includes the generation, emission, transmission, modulation, signal processing, switching, amplification, detection and sensing of light.*

Photonic - of, or relating to photons or to photonicsen.wiktionary.org/wiki/photonic

Introduction

* Wikipedia. The Free Encyclopedia

Photonics is the study or application of electromagnetic energy whose basic unit is the photon, incorporating optics, laser technology, electrical deviceswww.vpl.ca/bcscienceclusters/glossary.html

The technology of transmission, control, and detection of light (photons). This is also known as fiber optics and optoelectronics.techresearch.intel.com/articles/Tera-Scale/1609.htm

The science of manipulating photonswww.nanotech-industries.com/industry-terms.php

Introduction

*It appeared in the late 1960s to describe a research field whose goal was to use light to perform functions that traditionally fell within the typical domain of electronics, such as telecommunications, information processing, etc.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon.www.timbercon.com/Fiber-Optic-Glossary/alphabet-process.html

Photonic - a term coined for devices that work using photons or light. It is analogous to "electronic" for devices that work with electrons.www.assemblymag.com/CDA/Articles/Web_Exclusive/0e5a2fdd9c5c901

Introduction

* Wikipedia. The Free Encyclopedia*

"Photonics was originally introduced as a counterpart of electronics - using photons instead of electrons to process and transfer signals and information - but now the meaning of photonics is gradually becoming wider."

Electronics: First transistor (’40).

Photonics: Still appearing lasers (’60). Potentiality illimited.

Projects

Photonic crystals are periodic opticalnanostructures that are designed to affect the motion of photons in a similar way that periodicity of a semiconductor crystal affects the motion of electrons. Photonic crystals occur in nature and in various forms have been studied scientifically for the last 100 years.*
