We performed extensive characterization of all-optical packet envelope detection circuit for ultra-fast packet switched networks. Correct operation with RZ-format data pulses is experimentally demonstrated over a broad range of input packets' wavelengths and power levels.
In order to meet the ever-increasing demand of data communication for future optical networks and optical computing, high-speed photonic digital processing is required. Elementary blocks, performing basic operations are the building elements for more complex subsystems implementing all-optical digital processing. These functions include elementary optical logic gates as well as complex photonic combinatorial...
We propose a cost-effective implementation of reconfigurable add&drop functionality in Optical Cross Connects based on the concept of common add&drop in the node (OXC with per- Node Add&Drop, OXC-NAD). The proposed architecture constrains usable transponders wavelengths, but the analysis on significant mesh topologies demonstrates that this does not affect the behavior of the transparent...
Reconfigurable optical add-drop multiplexer (ROADM) is a key network element enabling flexible handling of wavelengths. Its architecture allows for remote traffic provisioning at the wavelength level in network node, better utilization of transmission bandwidth, operation cost reduction, simplification of network design and implementation. In this talk we present recent results on the investigation...
