Latest Patents
Zameer Ul Hasan's latest patents involve the use of II-VI compounds as a medium for optical data storage through fast persistent high-density spectral holeburning. This process utilizes two-photon ionization of rare earth ions, selected by a narrow band laser, to create narrow regions of reduced absorption in the absorption spectrum of a rare earth ion. These optical holes are crucial for applications such as high-density re-writable or photo-erasable memory, spectral holographic memory, and communication. His inventive practice has successfully burned two hundred forty photon-gated spectral holes in the zero phonon line of the 4f-5d transition of Eu in a magnesium sulfide host. Materials like CaS:Eu, CaS:Eu,Sm, and MgS:Eu have demonstrated a very high density of spectral holes, showcasing the potential of these compounds in advanced memory technologies.
