Abstract: A method for carrying data on a live host signal, comprising the steps of: varying timing in a host signal in response to data to be encoded, wherein variations in timing are smaller than a sampling period for detection and capture of the digital signal receiving the live host signal; sensing pulse timing variations in the received live host signal by comparison to a reference signal; and determining information in the sensed timing variations.

Abstract: A system for transmitting data using orthogonal mode division multiplexing (OMDM), a multiplexing method derived from the orbital angular momentum of photons. In one embodiment, a transmitter transmits multiple superimposed radio frequency (RF) beams each independently modulated with data, and each with a different orbital angular momentum rotational state. An OMDM receiver receives the different rotational states in separate communications channels. The OMDM states are substantially orthogonal, providing independent data channels for increased data capacity, and providing privacy.

Abstract: Imaging systems and methods for simultaneous real and Fourier plane imaging. In one example, an imaging system includes at least one optical element configured to receive and focus incident electromagnetic radiation from a viewed scene, a first detector positioned at an image plane of the at least one optical element and configured to produce a first image of the viewed scene, and a second detector positioned at a Fourier plane of the at least one optical element and configured to produce a second image of the viewed scene, the first and second detectors configured to receive the electromagnetic radiation and produce the first and second images, respectively. The system may additionally include an optical component, such as a beamsplitter, for example, configured to divide and direct the incident electromagnetic radiation to the first and second detectors.

Abstract: A method includes providing outgoing optical signals for transmission by a monostatic optical terminal using multiple transmit channels and providing incoming optical signals obtained by the monostatic optical terminal to multiple receive channels. The method also includes using a polarization beam splitter/combiner to combine the outgoing optical signals into a combined outgoing optical signal and to split a combined incoming optical signal into the incoming optical signals. The method further includes using at least one feedback loop to adjust an aim or path of at least one of the outgoing optical signals or at least one of the incoming optical signals. The method may optionally include using an optical element to convert polarizations of the combined outgoing optical signal in order to generate an output signal and to convert polarizations of an input signal in order to generate the combined incoming optical signal.

Abstract: An apparatus includes polarization beamsplitters that each separate incoming and outgoing optical signals having different polarizations. The apparatus also includes directionally-dependent polarization rotation optical assemblies that each maintain a polarization of one of the incoming and outgoing optical signals and to rotate a polarization of another of the incoming and outgoing optical signals. The apparatus further includes a third polarization beamsplitter that combines the outgoing optical signals to produce transmit optical signals and separate receive optical signals to produce the incoming optical signals.

Abstract: A demodulator can include an optical resonator. The optical resonator can include a resonant cavity that extends between a first surface that is partially reflective and a second surface that is at least partially reflective. The first surface can receive a phase-modulated optical signal that has a time-varying phase. The resonant cavity can accumulate resonant optical signal energy based at least in part on the phase-modulated optical signal. The first surface can direct a fraction of the resonant optical signal energy out of the optical resonator to form an intensity-modulated optical signal that has a time-varying intensity. A data detector can receive at least a portion of the intensity-modulated optical signal and, in response, generate an intensity-modulated electrical signal that has a time-varying intensity that corresponds to the time-varying phase of the phase-modulated optical signal.

Abstract: Antennas and other transducers for use in transmitting and receiving twisted waves are disclosed. A reflector includes numerous parabolic segments having focal lengths that decrease monotonically with azimuth angle. A feed is used that is located at a focal length associated with one of the segments. Thus, each segment has a phase delay that is related to a difference between the primary focal length and the focal length of the segment. This variation of phase delay with azimuth allows twisted waves to be transmitted and received.

Abstract: An apparatus includes multiple dual cladding waveguides each having a single-mode interior section that transports one of multiple outgoing optical signals and a multimode section at least partially surrounding the interior section that transports one of multiple incoming optical signals. Different outgoing signals have different polarizations, and different incoming signals have different polarizations. The apparatus also includes a polarization beamsplitter that combines the multiple outgoing signals to produce transmit optical signals and separates receive optical signals to produce the multiple incoming signals.
