An optical switch device includes a first array (20) of reflectors (22),
each associated with a separate optical fiber input (12), and a second
array (30) of reflectors (32), each associated with a separate fiber
output (14). The reflectors (22 and 32) are positionable to direct an
optical signal from any one of the fiber inputs (12) to any one of the
fiber outputs (14). The optical signal is directed along an optical
pathway between the desired fiber output (14) and its associated
reflector that is substantially aligned with an axis extending centrally
from the fiber output. Preferably, symmetrical fiber beam forming units
for forming the optical signal into a focused beam are included between
the fiber inputs (12) and the first array as well as between the second
array (20) and the fiber outputs (14). A method for switching optical
signals between an input and an output optical fiber end involves forming
the optical signal emitted from the input fiber end into a focused beam
wherein rays from a point on the input fiber end are convergent. The
focused beam is directed towards the output fiber end using at least two
positionable reflectors oriented to direct the signal so that, prior to
reaching the fiber output, it propagates along an optical pathway that is
substantially aligned with an axis extending centrally from the output
fiber end.
