Investigation on impact of multilevel modulation techniques over various types of all optical gray code converters for Tbps applications

Abstract

The development of telecommunication systems aids the demand of internet of things big data deep learning autonomous driving crypto currencies data centers neuromorphic computing wearable systems and numerous other applications The limitation of Moore s Law and the consequent physical downfall of conventional CMOS circuit miniaturization have inspired a current pursuit for emerging technologies to support high speed data processing reduced power consumption and low energy dissipation For the emerging telecommunication industry the entire communication system to be all optical to support the increasingly complex mathematical and technical problems The novel mass producible intermediary components for telecommunication and sensing applications demands all optical logic gate based devices capable of manipulating input signals at ultra fast speed of Tbps range Photonics is a new technology capable of replacing the gaps in digital electronics and accomplishing the previously listed features To meet the requirements of such telecommunication system novel all optical Binary to Gray Code BTG converter and BCD to Gray Code BCTG converter are proposed in this thesis as they are widely employed as cyclic codes to facilitate error correction In general Semiconductor Optical Amplifier SOA based techniques exhibit significant advantages like less power consumption high integration possibility in the design of all optical devices The advantages of nonlinear effects such as Cross Phase Modulation XPM of this SOA element can be used in several applications such as format conversion wavelength conversion and switching newline
