An optical switch with a compact form factor includes a multiple-fiber
collimator and an angle tuning element for deflecting an optical beam
from an input fiber into one of at least two output fibers. The angle
tuning element may be provided between a pair of coaxially-aligned
collimators, one of which is the multiple-fiber collimator.
Alternatively, the angle tuning element may be provided between the
multiple-fiber collimator and a reflective surface, so that only one
collimator is required and the optical switch may be designed to have its
input and output ports on the same side.
