Abstract: A high gain non-mechanical steerable beamforming antenna is provided together with a system implementing the antenna. The steerable beamforming antenna uses a reflectarray structure in conjunction with a phased array antenna element configuration. The antenna elements may include micro particle arrays (MPAs), having a number of micro particles disposed thereon. The micro particles may be implemented as graphene elements or as plasmonic elements having a sufficiently high electron mobility and an electron carrier density that is controlled as a function of an applied electronic tuning signal. The change in electron carrier density of the MPA elements, in turn, causes a phase change in incident waves provided by a source feed, facilitating steering of a main beam of an antenna pattern associated with the reflected incident waves.

Abstract: Systems and techniques are disclosed for flat-top intensity laser sheet beam generation. The system includes a source of light directed at a first optical component arranged to receive the light and generate spherical aberration (e.g., third order positive aberration) in the light rays. The spherical aberration results in positive aberrations in the light in a first plane and also results in the light being substantially collimated in a second plane perpendicular to the first plane. In some cases, the source of light is provided from a laser diode and the first optical component is one of an aspherical lens and a spherical lens. The system also includes a second optical component for focusing the light in the second plane. In some cases, the second optical component is a cylindrical lens.

Abstract: Techniques and mechanisms for a monolithic photonic integrated circuit (PIC) to provide spectrometry functionality. In an embodiment, the PIC comprises a photonic device, a first waveguide and a second waveguide, wherein one of the first waveguide and the second waveguide includes a released portion which is free to move relative to a substrate of the PIC. During a metering cycle to evaluate a material under test, control logic operates an actuator to successively configure a plurality of positions of the released portion relative to the photonic device. In another embodiment, light from the first waveguide is variously diffracted by a grating of the photonic device during the metering cycle, where portions of the light are directed into the second waveguide. Different wavelengths of light diffracted into the second waveguide may be successively detected, for different positions of the released portion, to determine spectrometric measurements over a range of wavelength.
