The holographic optical switches are three-dimensional devices, having the characteristics of flexibility and compactness. The procedure to realize a 4×4 active splitter and active combiner network with holographic optical switches is discussed in detail. After optimum design, the unique features of compactness and flexibility of holographic optical switches not only significantly saves space o...

Today’s communication WDM or OTDM networks, packetor circuit-switched, are characterized by hybrid architectures. In these architectures, electronic nodes are connected by optical links and switching is usually performed electronically using optoelectronic devices. However, the relatively low transmission bandwidth of the electronics and the associated optoelectronic interfaces, present an obst...

Optical switches and wavelength converters are recognized as two of the most important DWDM system components in future all-optical networks. Optical switches perform the key functions of flexible routing, reconfigurable optical cross-connect (OXC), network protection and restoration, etc. in optical networks. Wavelength Converters are used to shift one incoming wavelength to another outgoing w...

Constructing multi-Terabit switches and routers entirely out of electronic cross-bars require multiple racks of switches and huge number of interconnects. The cost and power consumption of such a system is very high and has a limited scalability. The all-optical switching has the problem of buffering and processing and the construction of multi-terabit switches and routers based on all-optical ...

This is technical report outlining an idea for basic long term research into the architectures for programmable all-optical Internet routers. We are revisiting some of the fundamental tenets of computer science to carry out this work, and so it is necessarily highly speculative. Currently, the processing elements in all-electronic routers are typically fairly conventional von-Neumann architectu...
