Time control sequences of optical switches from S1 to S9. T and R mean that the optical switches are transmitted and reflected, respectively. Δ T is the photon pulse width, which should be far more less than the interval ( L 1 – L 0)/ c . Thus, Δ t ≃( L 1 – L 0)/ c , and Δ t 1≃ L D/ c . The time between S3 and S6 or between S3 and S8 should be much less than Δ t and have been ignored.
