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.

A system includes first signal processing circuitry to transmit a signal including a plurality of data streams over a link. The first signal processing circuitry generates a plurality of composite data streams by overlaying at least one first data signal of the plurality of data signals in a first data layer with at least one second data signal of the plurality of data signals in a second data layer. Second circuitry processes the plurality of composite data streams to associate with each of the plurality of composite data streams a function to provide minimization of a time-bandwidth product of the plurality of composite data streams to enable transmission of each of the plurality of composite data streams on the link at a same time.

An apparatus for performing an endoscopic procedure for detecting cancerous tissue includes a detection probe for detecting the cancerous tissue. The detection probe includes a first fiber for emitting an ultraviolet light beam having an orthogonal function applied thereto and a second fiber for receiving emissions from tissues responsive to the ultraviolet light beam emitted for the first fiber. An ultraviolet emission source generates the ultraviolet light beam. Orthogonal function circuitry applies the orthogonal function twist to the ultraviolet light beam. Detection circuitry detects fluorescence and orthogonal function within the emissions from the tissues received over the second fiber.

An apparatus detects a material within a sample and includes signal generation circuitry that generates a first light beam having at least one orbital angular momentum applied thereto and applies the first beam to the sample. The orbital angular momentum imparts a phase factor of exp(imφ), where m is at least one of an integer value or fractional value and φ is the azimuth angle, 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.

Quantum key processing circuitry generates a secret key for transmission to second circuitry using a quantum key generation process and for encoding the plurality of data streams for transmission on the link using the generated secret key. Third circuitry transmits the encoded plurality of data streams on the link.

An apparatus for identifying a concentration of a specific material within a first material includes an input for receiving a signal after the signal passes through the first material. The signal has at least one orthogonal function therein and the at least one orthogonal function comprises at least one of an orbital angular momentum function or a Laguerre-Gaussian function. A detector detects the at least one orthogonal function within the signal, determines the concentration of the specific material within the first material based upon the detected at least one orthogonal function and generates an indication responsive to the determination. An output provides for an output of the generated indication.

The present invention as disclosed and described herein, in one aspect thereof, comprises a method for multiple access communications over a communications link involves receiving a plurality of data streams from a plurality of data sources. The plurality of data streams are grouped into a plurality of groups. Orthogonal frequency division multiplexing (OFDM) processing is applied to each of the plurality of groups. Each of the plurality of groups uses a same combination of frequency and time slot combinations in the OFDM processing. A different orthogonal function is applied to each of the OFDM processed groups to uniquely identify each of the OFDM processed group from each other and the orthogonal function processed groups are transmitted over the communications link.
