“…The IBWR switch consists of a buffering section connected to a non-blocking switching section. The buffering section contains M delay lines, of sizes from 0 to M-1 slots, nN Tunable Wavelength Converters (TWC) [5] with a tuning range of λ 0 ...λ K-1 , K=max (nN,M) and two K×K ArrayedWaveguide-Gratings (AWG) [6]. The routing properties of AWG devices make packets from input port i leave the buffering section at the i-th output port, independently of the wavelength conversion applied.…”

“…It is based on Arrayed-Waveguide Grating (AWG) multiplexers (Takahashi et al, 1990;Dragone, 1991;AbRahman et al, 2009) and wavelength conversion techniques (Durhuus et al, 1996;Glance et al, 1993). In order to explain the operation of this kind of buffer, we should first explain the wavelength routing model of an AWG.…”

Problem statement: Optical Packet Switching (OPS) and transmission networks based on Wavelength Division Multiplexing (WDM) have been increasingly deployed in the Internet infrastructure over the last decade in order to meet the huge increasing demand for bandwidth. Several different technologies have been developed for optical packet switching such as space switches, broadcast-and-select, input buffered switches and output buffered switches. These architectures vary based on several parameters such as the way of optical buffering, the placement of optical buffers, the way of solving the external blocking inherited from switching technologies in general and the components used to implement WDM. Approach: This study surveys most of the exiting optical packet switching architectures. A simulation-based comparison of input buffered and output buffered architectures were presented. Results: The performance analysis of the selected two architectures derived using simulation program and compared at different scenarios. We found that the output buffered architectures give better performance than input buffered architectures. Conclusion: The simulation results shows that the-broadcast-and-select architecture is attractive in terms that it has lees number of components compared to other switches.

Abstract.A comparative study, in aspects of both wavelength dependence and fabrication tolerance, is carried out between silica-based phase shifters designed in two different regime, namely length difference regime and refractive index difference regime. Results show that in the wavelength range of 1500-1600 nm, phase shifter designed in refractive index difference regime has a working wavelength range 2.8~3.1 times wide as that designed in length difference regime; while in the aspect of fabrication tolerance, phase designed in length difference regime is advantageous, with respect to waveguide core dimension error, and waveguide core refractive index error as well.
