Optical and nonlinear-optical properties of negativeindex nanocomposite as well as the feasibility of a design of novel photonic microdevices and all-optical data processing chips are numerically simulated. Keywords—Numerical simulation, nano materials and nanostructures, negative-index metamaterials, nanophotonics, nano and micro devices, all-optical switches, optical frequency narrow-band fil...

In all-optical networks, signals are propagated through switches with no electrical regeneration. The switches used in all-optical networks are prone to signal leaking; due to the absence of electrical regeneration, these leaked signals, called crosstalk signals, may therefore propagate through hundreds to several thousands of kilometers. Crosstalk may be enhanced by fiber nonlinearities during...

Photonic packet switches offer the high speed, data rate and format transparency, and flexibility required by future computer communications and cell-based telecommunications networks. We review experimental progress in Multiwavelength photonic packet switches with an emphasis on all-optical guided wave systems. The term all-optical implies that the data portion of a packet remains in optical f...

All optical networks and switches are envisioned as a solution to the increasing complexity and power consumption of today’s communication networks who rely on optical fibers for the transmission of information but use electronics at the connecting points on the network (nodes) to perform the switching operation. All optical networks, in contrast, will use simple signalling methods to trigger a...
