Extensive research has been carried out on the performance investigation of two-dimensional wavelength hopping/time spreading optical code division multiple access (OCDMA) codes, which are based on picosecond multiwavelength pulses under the influence of temperature variations resulting from changing environmental conditions. Equations have been derived to(More)
In a fast changing world where information technology drives economic prosperity, the number of data centres has grown significantly in the past few years. These data centres require large amount of energy in order to meet up with increasing demands. An overview of energy efficient optical interconnects as a means of reducing energy consumption without(More)
Since its emergence the internet has been a significant part of today's modern living. Defined by its interconnections and routing policies, it has fuelled increased demands for provisioning of new more advanced services that are able to dynamically react to changes within the network. These services however, lead to enormous energy consumption in contrast(More)
() 1 The most common metric for evaluating the performance of an optical communications system is the symbol error probability (SEP) versus the received optical power. In circuit-like optical systems employing binary transmission such as WDM, this SEP takes the form of the Bit Error Rate (BER) which is, in general, relatively constant. However, when(More)
This paper presents results of our extensive investigation of OCDMA system performance under the influence of varying transmission link chromatic dispersion. The investigations were carried out using incoherent 2-dimensional wavelength-hopping/time-spreading (2D-WH/TS) OCDMA codes based on picosecond pulses on a 17 km long bidirectional fiber link installed(More)
Increased temperature and perspiration within a prosthetic socket is a common complaint of many amputees. The heat dissipation in prosthetic sockets is greatly influenced by the thermal conductive properties of the socket and interface liner materials. These materials influence the body's temperature regulation mechanism and might be the reason for thermal(More)
We present the architecture and code design for a highly scalable, 2.5 Gb/s per user optical code division multiple access (OCDMA) system. The system is scalable to 100 potential and more than 10 simultaneous users, each with a bit error rate (BER) of less than 10 −9. The system architecture uses a fast wavelength-hopping, time-spreading codes. Unlike(More)
The last mile solutions for high-speed high-capacity optical networks capable of securely supporting large number of simultaneous users by minimal hardware requirements are needed but it seems that any such solutions are still far away. Access networks based only on a wavelength-division multiplexing (WDM), optical timedivision multiplexing (OTDM) or(More)
We report the experimental observation of temporal vector soliton propagation and collision in a linearly birefringent optical fiber. To the best of the authors' knowledge, this is both the first demonstration of temporal vector solitons with two mutually incoherent component fields, and of vector soliton collisions in a Kerr nonlinear medium. Collisions(More)
