Using a 7.5 μm diameter disk fabricated with III-V-on-silicon fabrication technology, we demonstrate bias-free all-optical wavelength conversion for non-return-to-zero on-off keyed pseudorandom bit sequence (PRBS) data at the speed of 10 Gbits/s with an extinction ratio of more than 12 dB. The working principle of such a wavelength converter is based on free-carrier-induced refractive index mod...

Optical burst switching networks have received a lot of attention in the research community in the recent years. The JET protocol, first proposed by Qiao and Yoo in 1997 in [6, 5], is used for resource allocation in these networks. Up to the present, the JET protocol has been studied in networks that use wavelength conversion [7, 1]. In this paper the JET protocol is discussed in optical networ...

In this paper we report the ultrafast all-optical wavelength conversion in Silicon-onInsulator (SOI) waveguides. We used a pump-probe setup with 300 femtosecond pulses to demonstrate large temporal phase-shifts, caused by the Kerr effect and free carrier generation. Large wavelength shifts of a 1683nm probe signal have been observed. The wavelength conversion, ranging from 10nm redshifts to 15n...

100 Heuristic Algorithm of Allocation of Wavelength Convertible Nodes and Routing Coordination in All-Optical Networks Hiroaki Harai, Masayuki Murata and Hideo Miyahara Department of Informatics and Mathematical Science Graduate School of Engineering Science, Osaka University Toyonaka, Osaka 560-8531, Japan Abstract| It is true that in all-optical networks, network performance can be improved b...

Both classical and quantum systems utilize the interaction of light and matter across a wide range of energies. These systems are often not naturally compatible with one another and require a means of converting photons of dissimilar wavelengths to combine and exploit their different strengths. Here we theoretically propose and experimentally demonstrate coherent wavelength conversion of optica...

This paper provides an overview on efficient algorithms for multicasting in optical networks supported by Wavelength Division Multiplexing (WDM) with limited wavelength conversion. We classify the multicast problems according to offline and on-line in both reliable and unreliable networks. In each problem class, we present efficient algorithms for multicast and multiple multicast and show their...

It is true that in all-optical networks, network performance can be improved by wavelength conversion. However, the switching node with wavelength conversion capability is still costly, and the number of such nodes should be limited in the network. In this paper, a performance optimization problem is treated in all-optical networks. We propose a heuristic algorithm to minimize an overall blocki...
