U Ultra Wide Arrayed Waveguide Grating ( AWG ) Devices for Dense Wavelength Division Multiplexing

To meet the exploding demand for Internet and broad-band services, dense wavelength-division-multiplexing systems have been extended from long-haul transmission systems to metropolitan and access area networks. In such systems, compact and conventional arrayed-waveguide grating multi/demultiplexers are required to reduce the cost of the systems. The evolution of broadband services will depend on the widespread deployment of optical communication systems. The deployment of such systems will in turn, help drive increased demand for additional capacity. In this world, service providers will have a growing need to be able to flexibly adjust capacity to accommodate uncertain and growing demand. This paper has proposed ultra wide AWG devices for dense wavelength division multiplexing (DWDM) optical communication systems that deeply studied over wide range of affecting parameters. Two multiplexing methods are applied, space division multiplexing (SDM) and DWDM, where 300 to 600 transmitted channels are processed to handle the product of transmission bit rate for planar waveguide cables of multi links using soliton transmission technique and maximum time division multiplexing (MTDM).
