It is then possible to the phase of m+3 positions original optical signal sequence is obtained according to the phase of the signal sequence of m positions firstThe signal of the specific original signal sequence for how obtaining m+3 positions, process can be as follows：

Step 1：Phase { the b of the optical signal of any given preceding 3 bit_-3,b_-2,b_-1}；

Step 2：Since the 4th of the first signal sequence, formula is used（2）Order obtains everybody of the sequence so as to obtain To the phase of follow-up all optical signals：

b_k=mod{r_k-b_k-1-b_k-2-b_k-3, 4 }, k=0,1,2 ..., m-1 formula（2）

It will be apparent from the above that according to different initial 3 optical signal sequences, 64 kinds of input signal sequences are shared by 1:4 Required output signal is obtained after light splitting and interference.
