Abstract:
We discuss an emerging monolithic “photonic integrated circuit” technology for application in future wavelength division multiplexed (WDM) networks. Based on a planar reflection-grating wavelength multiplexer/demultiplexer, and realized in InP-matched material for the long wavelength fiber band, the WDM optical cavity may be integrated with different active elements to provide a variety of spectrally-matched WDM functional components. We consider the design and performance of the basic mux/demux, and review the current status of both the passive device and integrated active components. We also

Abstract:
Mode multiplexers/demultiplexers (MUX/deMUX) are key components in mode division multiplexing. A silica waveguide mode MUX consisting of four cascaded directional couplers is experimentally demonstrated. The beam propagation method is used in the device design and optimization. Thermal oxidation, plasma-enhanced chemical vapor deposition, and ultraviolet photolithography are adopted in the silica waveguide mode MUX fabrication. The measurement results prove that the input E00 mode can be selectively converted to E10 mode, E20 mode, and E30 mode. Within the wavelength range of 1500 to 1620 nm,

Abstract:
Survivability becomes increasingly critical in managing high-speed networks as data traffic continues to grow in both size and importance. In addition, the impact of failures is exacerbated by the higher data rates available in optical networks. The purpose of this study is to optimize the survivability approach to address the problem of capacity efficiency and fast recovery time of multiple link and node failures in one technique. Most research works done had only addressed either of these constraints in a single failure. This research intends to develop and implement a new integrated approac

AbstractA pulse can be viewed as a kind of memory with faster processing elements, because the information carried by the pulse can be read out at any time by the faster processing elements. Taking this into consideration, one of the authors proposed a TDM switching system which in principle requires no random access memories, but rather only logical gates. This is very much suited to the photonic TDM switching system, as optical RAMs are not as yet available.This paper newly proposes a photonic TDM switching system in which a time jumper is placed on a highway link connecting multistage varia

On-chip optical dispersion compensation and wavelength division multiplexing/demultiplexing (WDM) are highly demanded functions for optical communications. In this work, we proposed a multichannel dispersion compensation structure based on chirped multimode grating within a counter-directional coupler (CMG-CDC). Simultaneous wavelength division multiplexing and demultiplexing can be realized within a compact footprint. A device design for four-channel CMG-CDC at the C/L (1530–1565 nm) band is presented with a channel spacing of 20 nm assisted by a grooved multimode waveguide structure. The ave

Abstract:
It has been proved that the use of multiplexers and demultiplexers of the smallest size has improved reliability to an extent but the effect of using bigger-sized MUX and DEMUX on reliability and fault tolerance must also be evaluated. In the recent past, the consequences of using higher-sized MUXs and DEMUXs have been explored and presented in this chapter. The full analysis of the size of MUXs and DEMUXs to be used so as to increase the reliability of the network to the optimum level has been presented. The analysis done on SEN MIN shows that the best size of MUXs and DEMUXs to be used is 4×1 and 1×4 respectively and hence the SEN MIN with 4×1 MUX and 1×4 DEMUX is named Fault Tolerance SEN MIN (FTSM).

Abstract:
Nano industries have been successful trendsetters for the past 30 years, in escalating the speed and dropping the power necessities of nanoelectronic devices. According to Moore's law and the assessment created by the international technology roadmap for semiconductors, beyond 2020, there will be considerable restrictions in manufacturing IC's based on CMOS technologies. As a result, the next prototype to get over these effects is quantum-dot cellular automata (QCA). In this chapter, an efficient quantum cellular automata (QCA) based random number generator (RNG) is proposed. QCA is an innovative technology in the nano regime which guarantees large device density, less power dissipation, and minimal size as compared to the various CMOS technologies. With the aim to maximise the randomness in the proposed nano communication, a linear feedback shift register (LFSR) keyed multiplexer with ring oscillators is developed. The developed RNG is simulated using a quantum cellular automata (QCA) simulator tool.
