摘要: A system contains a light source for generating a plane wave light beam. A MicroElectroMechanical (MEM) system includes an array of micro-mirrors for generating a light beam having a plurality of orbital angular momentum modes multiplexed together within the light beam responsive to the plane wave light beam and control signals for controlling the array of micro-mirrors. A controller generates the control signals to dynamically control a position of each of a plurality of micro-mirrors of the array of micro-mirrors to apply the plurality of orbital angular momentum modes on to the light beam. The controller controls the position of the plurality of micro-mirrors to dynamically generate a plurality of holograms for dynamically applying the plurality orbital angular momentum modes to the plane wave light beam and to dynamically encode a phase and amplitude of the light beam responsive to the control signals.

摘要: A system for enabling signal penetration into a building includes a first transceiver, located on an outside of the building, for transmitting and receiving signals at a first frequency outside of the building, wherein the signals at the first frequency do not easily penetrate into an interior of the building. A first up/down converter converts between a first version of the signals at the first frequency and a second version of the signals at a second frequency. The first frequency is higher than the second frequency and the signals at the second frequency better penetrate to the interior of the building and overcome losses caused by penetrating into an interior of the building. A second up/down converter converts between the second version of the signals at the second frequency that overcomes the losses caused by penetrating into the interior of the building and a third version of the signals after transmission from the building exterior to the building interior. A router transmits and receives the third version of the signals within the interior of the building.

摘要: An apparatus that detects a material within a sample includes signal generation circuitry that generates a first light beam having at least one fractional orbital angular momentum applied thereto and applies the first light beam to the sample. The at least one fractional orbital angular momentum imparts a phase factor to the first light beam. The orbital angular momentum generation circuitry includes a spiral phase plate having fraction step height to impart the at least one angular momentum to the first light beam. A detector receives the first light beam after the first light beam passes through the sample and detects the material responsive to a detection of a predetermined phase factor within the first light beam received from the sample.

摘要: A method for transmission of orbital angular momentum (OAM) data over an optical fiber involves generating an optical signal at a selected wavelength. A ratio of a diameter of a core of the optical fiber to the selected wavelength of the optical signal enables transmission of a predetermined number of orbital angular momentum modes over the optical fiber. The optical signal is modulated with at least one input data stream and an OAM signal is applied to the modulated optical signal to generate the OAM data signal. The OAM data signal is transmitted over the optical fiber using a fiber launcher. A received OAM data signal is processed to extract the at least one input data stream.
