ABSTRACT:
A free-space optical switch for switching light beams between waveguides of planar lightwave circuits (PLCs). Switching is accomplished using a combination of lenses and micromirrors. The lenses and the controlled tilt of the micromirrors can establish a one-to-one interconnection path between waveguides of the PLCs.
