An optical control device allows switching of signals without mechanical
components. The device includes a first member; a second member; an
active stage between the first member and the second member, the active
stage including an electro-optical material; a first transmission region
for transmitting a first optical signal toward the first member; and a
second transmission region for transmitting a second optical signal
toward the second member. The index of refraction of the active stage can
be varied to either reflect both the first optical signal and the second
optical signal or to permit the transmission of the first optical signal
and the second optical signal through the first and second member. The
index of refraction can be controlled by an electric field associated
with the active stage. A method for using an optical control device is
also disclosed.
