Problems solved by technology

[0005] However, in the above methods, slight changes in some important parameters (such as pump current, optical injection energy and detuned injected light) will change the state of output polarization
At the same time, due to the instability of polarization conversion, the logic gates in the above method have poor stability
In addition, the above implementation schemes of laser chaotic logic gates are all realized under static conditions, and do not make full use of the rich patterns of laser chaos to realize reconfigurable dynamic chaotic logic gates
At the same time, the above-mentioned basic logic gate operations can only be applied to combinatorial logic photonic devices, and cannot be applied to all-optical digital chaotic combinatorial (bit) logic operations (such as all-optical chaotic adders, decoders, etc.)

Abstract

The invention relates to the field of photon equipment and especially relates to a reconfigurable dynamic full light chaos logic gate which comprises a tunable distribution-feedback laser device, a beam splitter, a vertical chamber surface emission laser device, an optical isolator, a polarization beam splitter, a first subtracter and a second subtracter. The reconfigurable dynamic full light chaos logic gate provided by the invention has the advantages that conversion between a full light chaos logic gate operation and each logic gate operation is achieved; specifically, operations of ''AND'' gate, ''NAND'' gate, ''OR'' gate, ''NOR'' gate, ''XOR'' gate, and ''XNOR'' gate operations as well as mutual conversion can be achieved; and the reconfigurable dynamic full light chaos logic gate can be generalized and applied to logic operations of a full light digital chaos combination.

Description

technical field [0001] The invention relates to the field of photonic devices, in particular to a reconfigurable dynamic all-optical chaotic logic gate. Background technique [0002] The chaotic attractor is a collection of countless unstable periodic orbits, and the rich dynamic behavior of the chaotic attractor is ergodic, which indicates that during the time evolution of the chaotic system, the system can reach any different positions embedded in the chaotic attractor. At each point within the neighborhood of stable periodic orbits, chaotic systems provide such flexibility for controlling and exploiting chaos by exploiting the rich patterns embedded in nonlinear dynamical systems to perform logical computational functions, such as implementing basic logic gates. Chaotic computing can provide a new reconstruction digital logic computing scheme. By slightly changing the system parameters, the chaotic system can switch between different logic gates, thereby realizing a dyna...
