Abstract
Feature Issue on Optical Interconnection Networks (OIN). Two-dimensional (2-D)
microelectromechanical system (MEMS) optical switches have the merits of easy
fabrication and high reliability. Since the optical signal loss is mainly
proportional to the length of signaling paths in the switches, current 2-D MEMS
optical switches that use a crossbar structure have a rather limited number of
ports. For larger 2-D MEMS optical switches, we may use nonrectangular topology
switching fabrics to shorten the internal signaling path or to recollimate the
optical signal segment by segment inside the switches. We discuss these approaches
from the aspect of implementation and routing control complexity.
