Embodiment 1

[0061] This embodiment provides a window 11 .

[0062] Wherein, the material of the window 11 includes light-absorbing controllable interchanging molecules, and the light-absorbing controllable interchanging molecules can switch between the first configuration molecule and the second configuration molecule. The first light absorption rate of the first configuration molecule is lower than its second light absorption rate, and the second light absorption rate of the second configuration molecule is lower than its first light absorption rate. When the first configuration molecule absorbs the second light but does not absorb the first light, the first configuration molecule can be converted into a second configuration molecule, and when the second configuration molecule absorbs the first light but does not absorb the second light, A molecule of the second configuration can be converted into a molecule of the first configuration.

[0063] Specifically, the light-absorbing controll...

Embodiment 2

[0067] Such as Figure 1A As shown, this embodiment provides a medium, including: a window 11 and a photosensitive part 12 .

[0068] Wherein, the window 11 may be the window 11 in the first embodiment, but the shape of the window 11 is not limited to the polymer solid film layer. The photosensitive recording component is included in the material of the photosensitive part 12 . The light-sensitive recording component is only sensitive to the second light, and after absorbing the photon energy of the second light, the light-sensitive recording component produces a record information point that can be stably recorded.

[0069] Specifically, the photosensitive part 12 includes a polymer solid film layer, and the polymer solid film layer includes a light-sensitive recording component, and the light-sensitive recording component includes a molecular switch controllable fluorescent molecule, a photoacid generator, and a fluorescent precursor molecule. Molecular switches with photon...

Abstract

The invention provides a window, a medium and an optical storage method, the window comprises a polymer solid film layer, the material of the window comprises light absorption controllable interconversion molecules, and the light absorption controllable interconversion molecules are converted between first configuration molecules and second configuration molecules; wherein the absorptivity of thefirst light of the first configuration molecule is lower than that of the second light, and the absorptivity of the second light of the second configuration molecule is lower than that of the first light; when the first configuration molecule absorbs the second light but does not absorb the first light, the first configuration molecule is converted into a second configuration molecule, and when the second configuration molecule absorbs the first light but does not absorb the second light, the second configuration molecule is converted into the first configuration molecule. The medium includesa window and a photosensitive portion. The double-beam super-resolution optical principle is adopted, the super-resolution high-density technology is achieved in combination with the window, and the problem that the requirement of an existing double-beam technology for materials of a photosensitive part is high is solved.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a window, a medium and an optical storage method. Background technique [0002] Light has a wide range of applications in energy, electronics, communications, healthcare, etc., especially in the fields of information reading and writing, semiconductor manufacturing, information transmission, and optical microscopy. Due to the diffraction limit of light, the size of the area where light acts on the target cannot break through the limit of the diffraction limit. Therefore, the development of optical technology has been greatly hindered. [0003] In the prior art, there is a new double-beam super-resolution technology, which uses the excitation beam to induce photopolymerization on the target object, and a suppressing beam with a hollow focus to suppress the polymerization reaction in the overlapping area of ​​the exciting beam and the suppressing beam , so that the po...
