Techniques for optical packet switching and optical burst switching
IEEE Communications Magazine, 2001Wavelength-division multiplexing appears to be the solution of choice for providing a faster networking infrastructure that can meet the explosive growth of the Internet. Several different technologies have been developed so far for the transfer of data over WDM.

Leveraging MEMS's inherent advantages such as the batch fabrication technique, small size, integrability, and scalability, MEMS is positioned to become the dominant technology in optical crossconnect switches. MEMS optical switches with complex movable 3D mechanical structures, micro-actuators, and micro-optics can be monolithically integrated on the ...

Optical Buffering and Switching for Optical Packet Switching
2006 International Conference on Photonics in Switching, 2006We describe the design and initial results of an all-optical buffered 40 Gb/s packet switch. Dynamic packet forwarding is illustrated and specific attention is directed to buffering. We assess the challenges in meeting the requirements for optical buffering devices. Slow light and delay line buffering approaches are described and several recent results

2006 3rd International Conference on Broadband Communications, Networks and Systems, 2006
In this work, we evaluate an attractive candidate for optical network data transport: optical flow switching (OFS). We describe the operation and implementation of the architecture, characterize its capacity region and capacity-cost tradeoff, and compare it to other prominent optical network architectures.

Optical Switching in Chiropticenes
Annals of the New York Academy of Sciences, 2003Abstract: Chiropticenes™ are a novel class of predesigned chiral molecular switches that are triggered and controlled by a combination of both light and electric field. Chiropticenes contain an optically active (chiral) center and, as a consequence, provide two accessible equal energy bistable states resembling the molecular elements of binary logic ...

Optical Packet Switching and Optical Burst Switching
2020Optical transmission has long been the established choice for nonwireless data transmission spanning distances longer than a few tens of meters, due to its high bandwidth and electromagnetic noise immunity. Most current high-bandwidth networks are essentially a group of fiber-optic links connected by nodes whose function is to forward incoming data to ...

Optical Hybrid Switching – Combined Optical Burst Switching and Optical Circuit Switching
2004In this paper, we propose a new optical hybrid switching technique which combined Optical Burst Switching (OBS) and Optical Circuit Switching (OCS) using flow classification. In particular, this switching technique classifies incoming IP traffic flows into short-lived and long-lived flows for Quality of Service (QoS) provisioning according to traffic ...

Control of a MEMS optical switch
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004An analysis is performed of a MEMS optical switch to determine a dynamical model containing electrical, mechanical, and optical components. The model is compared to experimental results and shows a good match, aside from the damping term which is difficult to analyze.

Packet switching or optical switching?
IEEE Internet Computing, 2000One of history's main benefits is that it lets us detect trends that help predict the future. Over the past 30 years since the Internet started (1970-2000), many clear trends have emerged. The article very briefly examines the most critical of these trends, the one that led to the creation of the Internet: the packet switching cost trend.

Optical buffering and switching in packet switched optical networks
IEEE AFRICON. 6th Africon Conference in Africa,, 2003Optical packet switching provides the advantages of transparency and the efficient use of the bandwidth provided by WDM on optical transport networks. There are however various impediments to deploying this technology in an all-optical fashion: optical buffering is inefficient, and all-optical signal processing has not been implemented in networks.
