ABSTRACT:
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.
