Tunable fluidic lenses are utilizing curvature change via continuously adjusting injected liquid volumes to achieve variable-focusing properties. Nevertheless, the nature of curvature change and refractive index mismatch causes inherent spatial aberrations that severely degrade image quality. Here we present the experimental study of the aberrations in tunable fluidic lenses and use of adaptive optics...
An electronic dispersion compensation scheme based on coherent optical receiver and digital signal process is introduced in the fiber link timing distribution system. Then the timing error caused by dispersion can be significantly decreased.
A packet format employed in optical packet switching (OPS) networks is proposed. The performance of block synchronization of the burst-ode optical packets is analyzed. Based on the analysis, the length of overhead synchronization bits is optimized to achieve high framing efficiency.
