This paper focuses on the design and implementation of a low-complexity dialogue mechanism between the management and transport planes of an alloptical network. This dialogue aims at exchanging relevant information from monitoring the performance and degradation of optical signals with minimal disturbance to the optical services and minimum knowledge of the transport history of data, with a vie...

Recent advances in the development of photonic switching and transmission systems that exploit high and low index contrast integration materials are reported. Micro-ring resonators, delayed interferometers and alloptical wavelength converters integrated in Si3N4-SiO2 and silica-on-silicon substrates are used for the regeneration and wavelength routing of amplitude and phase modulated optical si...

This work assesses the prospects for high-speed alloptical wavelength conversion using the simple optical interaction with the gain in semiconductor optical amplifiers (SOA’s) via the interband carrier recombination. Operation and design guidelines for conversion speeds above 10 Gb/s are described and the various tradeoffs are discussed. Experiments at bit rates up to 40 Gb/s are presented for ...

Using the principle of quasi-continuous filtering in a non-linear fibre, we propose an optical device for the simultaneous regeneration of sevaral channels at 40 Gbit/s. Simulations predict an improvement of the signal quality for four channels by more than 6.8 dB.

Switch Allocation (SA) holds a critical stage in Network-on-Chip (NoC) routers, its performance gets affected adversely due to Head-of-Line (HoL) blocking. In traditionally used Input-Queued Routers (IQR), packets are arranged particular order each Virtual Channel (VC). This implementation is vulnerable HoL blocking, as the switch allocator can allocate only those which available at head VC. th...

In this paper a novel design of all-optical half-subtractor based on nonlinear directional coupler is proposed. By using four waveguides and appropriately adjusting the refractive indices and selecting the proper length of waveguides, halfsubtractor function can be obtained. The operation of this function is simulated by RSoft CAD-Layout (BeamPROP) simulator. The simulation results confirm the ...
