A space-diversity optical labeling scheme with optical labels derived from ASE noise

2009 7th International Conference on Information, Communications and Signal Processing (ICICS), 2009
We propose an optical labeling scheme whereby the optical label and payload are transmitted separately on two different fibers that carry bidirectional traffic. This eliminates the complex optical label and payload separation and combination processes which are usually required at the intermediate optical switching nodes.

Strategies for Label-Free Optical Detection

2007
A large number of methods using direct detection with label-free systems are known. They compete with the well-introduced fluorescence-based methods. However, recent applications take advantage of label-free detection in protein-protein interactions, high-throughput screening, and high-content screening.

Optical labelling through parametric amplification

2011 13th International Conference on Transparent Optical Networks, 2011
A new all-optical technique to label on-off keyed (OOK) payload signals is experimentally analysed. Such all-optical operation is accomplished by using a fibre optical parametric amplifier (FOPA) with the pump modulated by label information to amplify the OOK payload; as a result, the signal at the output of the FOPA becomes a ternary-amplitude optical

Adaptive optical label packet switching

SPIE Proceedings, 2007
This paper introduces a kind of Adaptive Optical Label Packet Switching (AOLPS) technology. Based on Optical Packet Switching (OPS), AOLPS uses optical label to achieve self-routing, and the size of optical packet is self-adaptive. At the edge nodes, IP packets are fist classified into different first-in-fist-out memories (FIFOs) according to their

Optical label switched networks

IEEE Communications Magazine, 2006
This article reviews the performance of an optical-label-controlled packet routing node as implemented in the European FP5-IST STOLAS project including a set of general engineering rules. Experimental networking scenarios and results from a STOLAS based network emulator supporting optical overspill routing are presented.

Optical-label-based all-optical packet switching routers

The Fourth Workshop on Photonics and Its Application, 2004., 2004
Current developments in optical components technologies enable wavelengths to be very narrowly spaced, transforming the optical fiber into a multi-terabit capacity medium. A new generation of "all-optical" cross-connects started to appear in the market leading to a number of advantages such as increased switching capacity, decreased overall network ...

Optical subcarrier label swapping by semiconductor optical amplifiers

Journal of Lightwave Technology, 2003
The semiconductor optical amplifier (SOA) can be used as an efficient high-speed modulator. This paper presents optical subcarrier multiplexed label swapping/reinsertion utilizing this device associated to the wavelength converter block in packet-switched all-optical networks. For that purpose, the modulation response and nonlinear behavior of SOAs are

Optical labeling using carrier suppressed second harmonic subcarrier label

Microwave and Optical Technology Letters, 2007
AbstractA carrier‐suppressed second harmonic subcarrier‐multiplexed labeling technique for optical label switching network is demonstrated. It provides frequency doubling for optical subcarrier label so that requirement for high bandwidth optical or electrical components can be reduced. The results of two‐span transmission of 10‐Gb/s payload with 1.244‐
