Abstract: The physical limitations of the amount of data stored on optical media are pushing researchers to create new materials and methods for recording and reading data. One of the promising areas is the use of fluorescent compounds. Within the framework of this work, polymer structures of optical fluorescent memory with a recording medium based on 3-(thiophene-2-carbonyl) -2- (furan-2-yl) -4n-chromen-4-one in polymethylmethacrylate have been fabricated and investigated. The concentration of chromone was 5% (wt.), Which during recording made it possible to achieve optical density values at λ = 442 nm in the range of 0.01 – 0.02 with a central layer thickness of 1-3 µm. In the structures developed, the process of two-photon information recording and fluorescent parallel reading is realized. The threshold recording power density for providing a two-photon process was (5.1 ± 0.4) 105 W/cm2.
