Abstract
A Michelson interferometer optical mirror switch is formed to include an optical signal path adjustment arrangement to transform the switch between a first, “pass through” state and a second, “reflective” state. A pair of input optical signal paths are coupled into an optical beam splitter that thereafter directs 50% of each optical signal toward a mirror element. The reflected signals then pass back through the beam splitter. If the optical path lengths are equal, an optical signal entering a first signal port will be coupled into a second signal port (the “pass through” state). If the optical path lengths differ by an odd, half-wavelength amount, the reflected signals will be directed back into the optical signal port of origin (the “reflective” state).
