In order to realize dynamic and reconfigurable optical chaotic logic operations， a specific technical scheme based on Vertical Cavity Surface Emitting Laser （VCSEL） feedback by its own light and linear electro-optic modulation effect has been proposed. The normalized injection current is modulated as logic input， the transverse electric field is modulated as control signal， and the logic output is demodulated by the difference between the average value and the threshold value of the x-polarized light intensity from the output of VCSEL. By transforming the logic operation relationship between control signal and logic input， the system can switch freely among basic logic operations such as NOT， AND， NAND， OR， NOR， XOR and XNOR. When the code width is 600 ps and the noise intensity is as high as 2.75×10⁹， the success probability of the logic operation still equals 1， indicating that the system has good anti-noise performance. And when the noise intensity equals 2.5×10⁹， the success probability always equals 1 if the code width is at least 579 ps. The above results have great reference value for the development of fast and stable combinational logic operation devices.
