Latest Patents

Daniel Rak holds a patent for a "Device for memory-storage of a coherent image in a multimode optical cavity." This innovative device utilizes a coherent light source to generate both a signal wave and a reference wave. These waves are directed through optical guiding devices that form a closed loop, allowing the signal wave to circulate. The guiding devices create a multimode optical cavity featuring a Fourier plane. Within this cavity, an amplifying interactive medium is strategically placed along the path of the signal wave. Here, the signal wave interferes with the reference wave, resulting in the creation of a diffraction grating. This process enables each signal wave to gain energy from the reference wave it interacts with. Additionally, a semi-transparent beam splitter is incorporated within the cavity to extract a portion of the energy from the optical cavity.
