Optical logic gates and method for generating logic signals using DNA-based nanostructure
An optical logic gate includes: a DNA based nanostructure including DNA and metal nanoparticles coupled to the DNA, the DNA based nanostructure being configured to rotate a polarization plane of an incident light; a polarizer to which light passing through the DNA based nanostructure is incident, the polarizer being configured to extract a component in a direction of a predetermined reference axis from light whose polarization plane is rotated by the DNA based nanostructure; and a detection unit to which light passing through the polarizer is incident, the detection unit being configured to generate a logic signal based on a result obtained by comparing the intensity of the component in the reference axis direction extracted by the polarizer with a predetermined threshold value.
