All-Optical Packet-Switching Decoder Design and Demonstration at 10 Gb/s

A 3 times 8 all-optical decoder based on cross-polarization modulation in semiconductor optical amplifiers is demonstrated for the first time to our knowledge. The design requires a single active optical device per output. Experimental results are shown for return-to-zero modulated 10-Gb/s signals. Applications include label processing in optical packet switched optical networks     

Navigation of a unicycle-like mobile robot for environmental extremum seeking

We consider a single Dubins-like mobile robot traveling with a constant longitudinal speed in a planar region supporting an unknown field distribution. A single sensor provides the distribution value at the current robot location. We present a new sliding mode navigation strategy that drives the robot to the location where the field distribution attains its maximum. The proposed control algorithm does not employ gradient estimation and is non-demanding with respect to both computation and motion. Its mathematically rigorous analysis and justification are provided. Simulation results confirm the applicability and performance of the proposed guidance approach.
