A photonic crystal all-optical anti-interference self-locking trigger switch comprising one photonic crystal structural unit (01), one optical switch (02), one internal or external wave-absorbing load (03), and one internal or external reference light source (04). The photonic crystal structural unit (01) consists of two input terminals (11 and 12), one output terminal (14), and one idle terminal (13). The first input terminal (11) of the photonic crystal structural unit (01) is connected to a logic signal. An input terminal of the optical switch (02) is connected to the reference light source (04). A first intermediate signal output terminal of the optical switch (02) is connected to a second input terminal (12) of the photonic crystal structural unit (01). The wave-absorbing load (03) is connected to a second intermediate signal output terminal of the optical switch (02). The photonic crystal all-optical anti-interference self-locking trigger switch is structurally simple and easy to manufacture, provides a high contrast between high and low logic outputs, a fast computing speed, and great anti-interference capability, and can be easily integrated with other optical logic elements.
