Abstract
A method for optically storing and retrieving information is provided that irradiates spin-defect centers in a substrate with red or blue light to change the charge state to form a pattern. This pattern encodes information and long-term data storage. The information is retrieved by irradiating the pattern with red light that causes the pattern to undergo fluorescence.
Claims20
A method for storing and retrieving information in a substrate, the method comprising steps of:
- irradiating spin-defect centers in a substrate with a first wavelength of light, the step of irradiating causing a plurality of the spin-defect centers to change from a first charge state to a second charge state, wherein the plurality of spin-defect centers with the second charge state centers are selected to form a first pattern that corresponds to predetermined information to be stored;
- and
- optically detecting the first pattern of spin-defect centers with the second charge state to thereby retrieve the predetermined information.
A method for storing information in a diamond substrate, the method comprising a step of:
- irradiating negatively charged nitrogen-vacancy (NV−) centers in a diamond substrate with a first wavelength of light, the first wavelength of light being selected from a red wavelength between 580 nm and 636 nm or a blue wavelength of light between 430 nm and 470 nm, the step of irradiating causing a plurality of negatively charged nitrogen-vacancy (NV−) centers to be altered by changing the plurality of negatively charged nitrogen-vacancy (NV−) centers to neutral NV0 centers, wherein the plurality of negatively charged nitrogen-vacancy (NV−) centers are selected to form a first pattern of neutral NV0 centers, the first pattern corresponds to predetermined information to be stored.
A method for storing information in a substrate with sub-diffraction resolution, the method comprising sequential steps of:
- selecting a target spin-defect center from a plurality of spin-defect centers which are disposed in a substrate, wherein the target-spin-defect centers is proximate peripheral spin-defect centers, the plurality of spin-defect centers forming a first pattern;
- irradiating the plurality of spin-defects centers, including the target spin-defect center, with a first wavelength of light, the step of irradiating changing a charge state of the target spin-defect center without altering nuclear spin states of either the target spin-defect center or the peripheral spin-defect centers, the step of irradiating causing the first pattern to change into a second pattern that corresponds to predetermined information;
- irradiating each peripheral spin-defect center, but not the target spin-defect center, with light to restore each peripheral spin-defect center's charge state based on each peripheral spin-defect center's nuclear spin state.
