Title:
MULTIFUNCTIONAL PHOTOELECTRIC LOGIC GATE BASED ON SINGLE LIGHT SOURCE AND SINGLE DETECTOR
Document Type and Number:
WIPO Patent Application WO/2023/241145
Kind Code:
A1
Abstract:
A multifunctional photoelectric logic gate based on a single light source and a single detector. A bipolar current response is achieved by regulating and controlling the polarization direction of light, and then logic determination is performed by means of the polarity of a signal current, so that the five basic logic functions of AND, OR, NOT, NAND and NOR can be completed by means of a single architecture, thereby greatly improving the integration level of the space and function of a photoelectric logic gate, reducing the complexity of a device, and strongly promoting the development of high integration, high precision, low power consumption and multiple functions of the photoelectric logic gate. Moreover, logic determination is performed by means of the polarity instead of the magnitude of a signal current, which is more conducive to the improvement in the accuracy of logic determination. Various logic functions are achieved by using polarization beam splitting of the same light source, such that the operation of the photoelectric logic gate is not affected by limited fluctuations of the power of the light source.
