Classification: CPC G | IPC G

Claim 6:
7. The straight waveguide phase change all-photonic Boolean logic device according to claim 1, wherein a detection signal is input into one end of the straight waveguide, an intensity of an optical signal output from the other end of the straight waveguide is detected and compared with an intensity of the input detection signal to determine transmittance of the two phase change functional units, so as to perform the reading operation on the two phase change functional units, the detection signal is an optical pulse or a continuous light with a relatively low power that does not change states of the two phase change functional units; through setting parameters of the Bragg grating, the detection signal is not affected by the Bragg grating.
