Introduction

Without any question, one of the utmost technological innovations of the twentieth 100 years has been the development of the incorporated electrical devices circuit (IC). Right after the look of the first incorporated silicon portion (developed by Jack Kilby at the Texas Instruments lab in 1958), the advantages of this revolutionary expertise over the discrete single-functional electronics produced directly apparent, and today it has made one of the most florid financial markets. The marvelous development of incorporated electronics was in a nice way forecast by Gordon E. Moore who was one of the Intel co-founder and a pioneer of the new incorporated technology. Moore empirically forecast the increasing two-fold of the transistor density on an incorporated portion every 18 months and he accepted that this tendency would have kept going for not less than one decade. It was the year 1969 [1]. As it is apparently illustrated by annals, the only error Moore pledged in his proposition was to underestimate the length of this explosive trend. Today, after more than four decades since Moore asserted his well renowned regulation, the yearly transistor output overwhelms the total number of transistors ever made up to that instant, for an international throughput that is hundreds times the number of ants on earth. However, regardless of the outstanding effort expended to hold miniaturizing the electrical devices microchips (IBM has lately broadcast the output of the world's least significant employed transistor with a 4nm silicon body and a 6nm barrier length) the integration method, that has let down the output charges and the power utilization of high pace electronics, is going to come to the personal restricts enforced by the electron-electron interaction happening on a sub-nanometric scale [2].

It is mostly for these causes that the world of research and expertise has tried to find new streets alternate to electronics. Because of its flexibility, and a certain stage of compatibility with the silicon expertise mostly engaged in the output of microelectronic circuits, optics appears to supply the most undertaking options to electrical devices schemes, particularly in telecommunication networks.  However, it is essential to hold in brain that today, for the most of applications; electronics is still adept to supply the identical advantages of optics at smaller cost. Even if optoelectronics has become a solid truth, “all-optical” technologies are still very costly, very convoluted, and/or consign less functionality. So, if electrical devices ICs are so cost-effective, and in general, technologically better, why was so much effort put into the development of optical telecommunication networks? The answer to this inquiry arises from the technological transformation that in the last 30 years has initiated the replacement of customary copper wires supportive the more effective optical fibers, particularly for long-distance communications. Today's optical connection systems effectively cover the long distances between localized telephones and supply the backbone for numerous other LANs (Local Area Networks), encompassing those utilized for twisted cord TV services, developed plants, and electric driven utilities interior high-tech ...
