The constructions of optical queues is one of the most critically sought after optical technologies in all-optical packet-switched networks, and constructing optical queues directly via optical switches and fiber delay lines (SDL) has received a lot of attention recently in the literature. A practical and challenging issue in the constructions of optical queues is on the fault tolerant capability...
A novel 2-to-l optical FIFO multiplexer under a simple packet routing policy, with maximum buffer size 2(n-2)-1, is proposed and experimentally demonstrated using an nxn arrayed waveguide grating (AWG) wavelength converters and fiber delay lines at 10 Gbps.
Planar photonic integrated circuits based on VCSEL are achieved by embedding an optical waveguide within the resonance cavity of the VCSEL, and utilizing diffraction grating couplers to efficiently diffract light from the VCSEL cavity into the waveguide in each lateral direction.
In this paper, we consider the construction of an optical priority queue with a single (M+1)times(M+1) switch and M fiber delay lines. The M fiber delay lines are connected from M outputs of the switch back to M inputs of the switch, leaving one input (resp. output) of the switch for the input (resp. output) of the priority queue. It was known that with an appropriate choice of the lengths of the...
