    Abstract: A communication system includes an OFDMA transmitter (Tx) at an optical line terminal (OLT) generating an OFDMA signal by assigning orthogonal subcarriers to different cell sites through digital logic, an electrical multiplexer combining the electrical OFDMA signal with two electrical clock signals, and an optical intensity modulator intensity-modulating the resulting joint electrical OFDMA+clocks signal; an optical multiplexer receiving aggregate OFDMA signals on multiple wavelengths with tight DWDM λ-spacing; a remote node (RN) receiving the OFDMA signals, such that each wavelength is distributed by a de-multiplexer (Demux) to designated general small cell area, to which cell sites are connected by optical splitters; and an optical network unit (ONU) to directly photodetect and digitize received OFDMA signal, wherein downstream (DS) information for each cell is digitally extracted and prepared for wireless radio frequency (RF) transmission over an air interface, and an electrical splitter and bandpass filters to separate the OFDMA and clock signals for DSP-free clock recovery.

    Abstract: A system and method for remote object sensing which features a spatially polarization-inhomogeneous light beam that is directed on the remote object. A polarimetry receiver receives the light beam after it contacts the remote object. The changes in the spatially polarization-inhomogeneous light beam from contacting the remote object are a result of spatial features of the remote object. The polarimetry receiver is configured to measure the spatially inhomogeneous electric field of the light beam after it contacts the remote object and compute the changes in the spatially polarization-inhomogeneous light beam in order to detect spatial features of the remote object. The system obtains high-resolution, real-time information concerning important spatial features of the remote object.

    Abstract: A method and system for remote sensing using optical orbital angular momentum (OAM)-based spectroscopy for lateral motion detection. The method includes applying an OAM mode on a light beam to generate an OAM light beam, the OAM light beam having an optical OAM spectrum, applying an OAM optical beam tilt on the OAM light beam to generate a tilted OAM light beam, transmitting the tilted OAM light beam on a remote object, such that the remote object interacts with the tilted OAM light beam, receiving a reflected OAM spectrum associated with the remote object, the reflected OAM spectrum having power values of OAM modes on opposite sides of an OAM launch mode, and displaying lateral motion of the remote object based on the reflected OAM spectrum by comparing the power values.

    Abstract: A system and method for network virtualization and resource allocation, including storing one or more received network requests in a request table, and updating at least one of a flow table, a waiting list table, or a candidate group map based on the one or more received network requests. The updating includes monitoring a transmission progress of each of one or more flows in a network of interconnected computing devices and moving completed flows from the flow table to a success list, moving requests in the waiting list table which have reached an attempt threshold from the flow table to a fail list, and compiling any residual requests in the waiting list with new requests to generate a new request table. A deterministic request allocation and/or an optimizing request allocation is performed based on the new request table.
