• REDOX-ACTIVE STRUCTURES AND DEVICES UTILIZING THE SAME
Patent number: 9309274
Abstract: A device is presented having reversibly changeable and optically readable optical properties. The device comprises a substrate having an electrically conductive surface and carrying a redox-active layer structure. The redox-active layer structure may be a monolayer or a multi-layer structure and is configured to have at least one predetermined electronic property including at least one of electro-density and oxidation state. The electronic property of the layer structure defines an optical property of the structure thereby determining an optical response of the structure to certain incident light. This at least one electronic property is changeable by subjecting the redox-active layer structure to an electric field or to a redox-active material. The device thus enables effecting a change in said electronic property that results in a detectable change in the optical response of the layer structure.

Patent number: 8917539
Abstract: A solid-state, multi-valued, molecular random access memory (RAM) device, comprising an electrically, optically and/or magnetically addressable unit, a memory reader, and a memory writer. The addressable unit comprises a conductive substrate; one or more layers of electrochromic, magnetic, redox-active, and/or photochromic materials deposited on the conductive substrate; and a conductive top layer deposited on top the one or more layers. The memory writer applies a plurality of predetermined values of potential biases or optical signals or magnetic fields to the unit, wherein each predetermined value applied results in a uniquely distinguishable optical, magnetic and/or electrical state of the unit, thus corresponding to a unique logical value. The memory reader reads the optical, magnetic and/or electrical state of the unit.

Patent number: 6549685
Abstract: A new electro-optic (EO) phase modulator constructed from a combination of a low-loss passive polymer waveguide and a self-assembled chromophore superlattice (SAS) with an intrinsically polar microstructure. In contrast to typical polymer-based modulators, the present invention utilizes a siloxane SA methodology that enables the acentric alignment of constituent chromophores during film growth without the need for post-deposition electric field poling. The guiding layer is constructed of the SAS and the glassy polymer Cyclotene™. The use of SiO2, Cytop™ and Cyclotene™ glassy polymers, results in a straightforward device fabrication process that is compatible with the thermally and photochemically robust SAS. Thus, nanoscale control of the film architecture results in greatly simplified macroscopic device fabrication. The present invention provides a SAS-based electro-optic modulator demonstrating excellent electro-optic response properties and a phase shift.
