The intensity ratios of signals in three demultiplexed channels change with the power of control field. (a) and (b) Relative delay time and intensity ratio between peak A and peak C. The read-out power keeps 8 mW. (c) and (d) Relative delay time and intensity ratio between peak A and peak B. The read-out power is 0.2 mW.
