AbstractWe propose a dial-up optical access architecture that allows an end host to dynamically request and receive a high-speed circuit for connection to its Internet Service Provider’s router. We carry out an analytical comparison of the current leased-line architecture and our proposed dial-up architecture for access networks. It shows significant capacity savings, for example, savings of 39...

We demonstrate here a spatially non-blocking optical 4x4 router with a footprint of 0.07 mm(2) for use in future integrated photonic interconnection networks. The device is dynamically switched using thermo-optically tuned silicon microring resonators with a wavelength shift to power ratio of 0.25nm/mW. The design can route four optical inputs to four outputs with individual bandwidths of up to...

Abstrac: We present simulation results of an ultrafast alloptical interferometric switching devices based upon the resonant nonlinearity in a semiconductor optical amplifier (SOA). We have investigated two configurations: one based upon a Sagnac interferometer and one based upon a MachZehnder interferometer. The switches have been used to model a 1x2 all-optical OTDM router. Simulation results ...

We propose a scheduling algorithm minimizing voids generated by arriving bursts in optical burst switched WDM network. In the proposed scheduling algorithm, when the burst which has arrived at optical core router at a certain time can be transmitted in some data channels by using the unused data channel capacity(it is called void), our proposed scheduling algorithm selects the data channel in w...

Divisor-Skip Wavelength Division Multiplexing (DS-WDM) ring is an optical interconnection network for workstation clusters or parallel machines which can connect various number of nodes easily using wavelength division multiplexing techniques. However, the wavelength-ordered routing algorithm proposed for the DS-WDM ring requires complicated processes in each router. Here, a new routing algorit...

The basic concepts of the ultrafast optoelectronic interface for superconducting digital electronics are presented. Several implementations of both the input optical-to-electrical and the output electrical-to-optical transducers are discussed. As an example, an optoelectronic telecommunication router is used that is capable of switching signals at a >100 Gbit s−1 rate on a single wavelength. We...

We demonstrate a regenerative optical grooming switch for buffer-less interconnection of metro/access and metro/core ring networks with switching functionality in time, space and wavelength domain. Key functionalities of the router are the traffic aggregation with time-slot interchanging (TSI) functionality, the WDM-to-ODTM multiplexing and the OTDM-to-WDM demultiplexing of high-speed channel i...

Traffic shaping at the edge router is one possible solution to mitigate the adverse effects of self-similar traffic in optical packet-switched networks. In this paper we propose an optical packet assembly mechanism and study its impacts on the traffic characteristics. In addition to the Hurst parameter, we apply new measures to describe the short-term correlation and to investigate the effect o...
