Abstract: The disclosed subject matter provides systems and methods for processing light. An example system can include one or more substrates, and a plurality of meta-units, which are patterned on each of the substrates and configured to modify a phase, an amplitude, or a polarization of the light with a subwavelength resolution. The system can be in a form of a diffractive neural network and be configured to perform target recognition.

Abstract: Hyperspectral resonant cavity imaging spectrometers and imaging systems incorporating the resonant cavity spectrometers are provided. The spectrometers include an array of photodetectors based on photosensitive semiconductor nanomembranes disposed between two dielectric spacers, each of the dielectric spacers having a thickness gradient along a lateral direction, such that the resonant cavity height differs for different photodetectors in the array.

Abstract: Disclosed herein are systems and methods for passively cooling water vapor to enable efficient condensation, and methods of making such systems. A passive cooler can include a thermally conductive substrate having a first side and a second side opposite the first side, a coating disposed on at least a portion of the first side of the substrate, and a housing having one or more insulative walls. The insulative walls may define a vapor flow channel from an inlet to an outlet of the housing such that the second side of the substrate is exposed to water vapor flowing through the vapor flow channel.

Abstract: A wavefront sensor system suitable for integration into an integrated circuit light detector may provide for wave angle sensors having varying functional relationships between the wave angle and signal to provide improved dynamic range. These wave angle sensors may be combined with integrated circuit phase angle sensors for a more complete analysis of the waveform.

Abstract: An optical field sensor is used to make phase measurements over an area of light reflected from an object outside a field of view of the light field sensor. These phase measurements are applied to a machine learning system trained with similar phase measurements from objects outside of a field of view to identify the object within a class of objects subject to the training.
