Abstract: An RF antenna feed module uses an optical feed network and photo-detectors to generate RF feed signals to drive a dual polarization RF antenna to produce an RF beam with a variable polarization state. The optical feed network and suitably the photo-detectors are monolithically fabricated PIC. Multiple modules may be configured to drive a dual polarization RF phased array. A single feed module can produce RF feed signals over a frequency range of at least 300 GHz.

Abstract: A DE energy weapon and tracking system includes a passive millimeter wave (PmmW) imaging receiver on a common gimbaled telescope to sense natural electromagnetic radiation from a mmW scene. The PmmW imaging receiver operates in a portion of the electromagnetic spectrum distinct from the IR bands associated with thermal blooming or the HEL laser. In the case of a HPM source, the reflected energy is either in a different RF band and/or of diminished amplitude such as to not interfere with operation of the PmmW imaging receiver. Although lower resolution than traditional optical imaging, PmmW imaging provides a viable alternative for target tracking when the DE weapon is actively prosecuting the target and provides additional tracking information when the DE weapon is not engaged.

Abstract: A sensing system. In some embodiments, the sensing system includes an imaging radio frequency receiver, an imaging radio frequency to optical converter, an imaging optical receiver, an optical beam combiner, and an imaging optical detector. The optical beam combiner is configured to combine an optical signal of the imaging radio frequency to optical converter, and an optical signal of the imaging optical receiver. In operation, the imaging radio frequency receiver, the imaging radio frequency to optical converter, and the optical beam combiner together form, on the imaging optical detector, an optical image of a radio frequency scene within a field of view of the imaging radio frequency receiver, and the imaging optical receiver and the optical beam combiner together form, on the imaging optical detector, an optical image of an optical scene within a field of view of the imaging optical receiver.

Abstract: An optical feed network (OFN) for an RF phased antenna array includes a single free-space optical beamformer that supports all of the RF electrical feed signals for the RF phased antenna array to steer an RF beam. The free-space optical beamformer can more easily scale to accommodate larger array sizes than either the discrete fiber channel or PIC implementations. Furthermore, certain embodiments of the optical beamformer avoid the complexity of having to compute FFTs for each channel to steer the beam, instead relying on the inherent function of an imaging lens to perform the FFT, which in turn facilitates rapid steering.

Abstract: An optically powered cryogenic FPA with an optical data link eliminates electrical penetrations of the cryogenic chamber for power delivery thereby reducing heat leaks into the cold volume by copper wires and EMI. An optical splitter receives and separates an optical input signal into an optical carrier signal, an optical Data IN signal and an optical power signal. An optical-to-electrical (O/E) converter converts the optical power signal into an electrical power signal, which is converted into a plurality of DC voltage signals to supply power within the chamber. An optical data link modulates the optical carrier signal with electrical signals from the ROIC to form and output an optical Data OUT signal.

Abstract: An RF imaging receiver using photonic spatial beam processing focuses a composite optical signal into a spot on an optical detector array to extract an image of an RF scene. The receiver steers the composite optical signal to move the location of the spot to increase the detected power in the image and selectively turns off one or more detector pixels around the spot to reduce noise in the image.
