Claim 5:
6. The straight waveguide phase change all-photonic Boolean logic device according to claim 1, wherein the optical pulse signal is input into a side of the straight waveguide where the first phase change functional unit is located, the first phase change functional unit heats up by absorbing the optical power thereby to induce the crystalline or amorphous phase change, so that the first phase change functional unit is finally in the crystalline state or in the amorphous state, so as to perform the write operation on the first phase change functional unit;
through setting parameters of the Bragg grating, after the optical pulse signal incident from one end of the straight waveguide passes through the Bragg grating, the transmitted optical pulse signal does not act on the second phase change functional unit on the other side of the straight waveguide.
