1. , a kind of complete light switch has:

  • The 1st input port, the flashlight of its input non-return-to-zero mode;

    The 2nd input port, its incoming carrier light;

    The the 1st and the 2nd light path;

    Dispenser, its be input to the above-mentioned the 1st and the light of the 2nd input port distribute to the above-mentioned the 1st and the 2nd light path respectively;

    The 1st non-linear optical element, it is arranged on above-mentioned the 1st light path, a branch of carrier wave light in a branch of flashlight and the carrier wave light that distributed by above-mentioned dispenser in the flashlight that input is distributed by above-mentioned dispenser, refractive index are because of above-mentioned a branch of flashlight but not linear variation and make the non-linear displacement of phase place of above-mentioned a branch of carrier wave light;

    The 2nd non-linear optical element, it is arranged on above-mentioned the 2nd light path, another Shu Zaibo light in another bundle flashlight and the carrier wave light that distributed by above-mentioned dispenser in the flashlight that input is distributed by above-mentioned dispenser, refractive index are because of above-mentioned another bundle flashlight but not linear variation and make the non-linear displacement of phase place of above-mentioned another Shu Zaibo light;

    Decay portion, it makes above-mentioned another bundle flashlight that is input to the above-mentioned the 2nd non-linear optical element also decay than the above-mentioned a branch of flashlight that is input to the above-mentioned the 1st non-linear optical element;

    Delay portion, it restraints flashlight to above-mentioned another of the above-mentioned the 2nd non-linear optical element input after the above-mentioned the 1st non-linear optical element is imported above-mentioned a branch of flashlight again;

    AndSynthetic portion, it is synthetic by the above-mentioned the 1st and the light of the 2nd light path,With the time of above-mentioned another bundle flashlight input of above-mentioned delay portion'"'"'s delay, also shorter than the relaxation time of the non-linear variations in refractive index in the above-mentioned the 1st and the 2nd non-linear optical element.
