Abstract
Optical switches can include collimator elements that accommodate two or more optical ports. This increases the number of ports the switch can accommodate without having to increase the size of other optical components within the switch. Separate deflectors can be used to accommodate optical signals from two different groups of ports. In some embodiments cross-coupling of signals between the two groups can be accomplished through use of re-direction optics.
