Abstract: Disclosed are embodiments photonic integrated circuits with photo-switchable components. Embodiments are illustrated in the form evanescent field perturbation sensors in which receptor molecules are patterned onto the sensor substrate with precision. In particular, light patterning and molecular-based photo-responsive motifs allow for the positioning of receptor molecules on the operational elements of the evanescent field perturbation sensors. Receptor molecules are further detachable from the sensor and capable of replacement with additional receptor molecules of the same type, or one or more alternative receptor molecules capable of receiving the same or different analyte receptor molecules. In certain embodiments the light sources for patterning and receptor molecule interchange may integrated within the sensor and/or sensor platform itself. In certain embodiments a method of recharging and/or reconfiguring the receptor molecules, and a machine for carrying out the method is disclosed.

Abstract: Optical imaging includes: configuring a spatial mode sorter to provide, in response to a received input optical signal, a separate output optical signal for each spatial mode in a set of target spatial modes: receiving a set of output optical signals from the spatial mode sorter during a detection interval of time: processing information based at least in part on the set of output optical signals received in the detection interval of time: and providing an estimated measurement for discriminating among a first set of two or more predetermined target images based at least in part on information derived from the processing. During the detection interval of time, a total number of the output optical signals is greater than two and less than ten.

Abstract: Imaging a distribution of one or more optical sources includes: receiving respective optical signals from a spatial mode sorter during each of two or more detection intervals of time; after each of the two or more detection intervals of time, processing information based at least in part on: (1) the respective optical signal received in the corresponding detection interval of time, and (2) a first set of models comprising a set of distributions related to one or more optical sources, each model corresponding to a different number of optical sources in the distribution, and configuring the spatial mode sorter based at least in part on the processing; and providing an estimated measurement characterizing the distribution of one or more optical sources based at least in part on the processed information. The processing after at least one of the two or more detection intervals of time includes computing an eigen-projection.

Abstract: Exemplary support assemblies may include a top puck defining a substrate support surface, where the top puck is also characterized by a height. The assemblies may include a stem coupled with the top puck on a second surface of the top puck opposite the substrate support surface. The assemblies may include an RF electrode embedded within the top puck proximate the substrate support surface. The assemblies may include a heater embedded within the top puck. The assemblies may also include a ground shield embedded within the top puck. The ground shield may be characterized by an inner region extending radially through the top puck. The ground shield may further be characterized by an outer region extending perpendicular to the inner region.

Abstract: A large aperture lightweight antenna uses an inflatable spherical surface deployed within a lighter than air platform. Beam steering is accomplished by moving the RF feedpoint(s) with respect to the reflector. The antenna can use an inflatable collapsible transreflector.

Abstract: Controlled phase shift in the operation of an RF antenna element is achieved by selectively choosing between different modes of antenna element resonance. Additional phase control resolution is achieved by combining this with other types of phase shifters. Such phase shifters are especially useful within a phased array of RF antenna radiator elements.
