Abstract: In some embodiments, a computer-implemented method for creating a fabricable segmented design for a physical device is provided. A computing system receives a design specification. The computing system generates a proposed segmented design based on the design specification. The computing system determines two or more loss values based on the proposed segmented design. The computing system combines the two or more loss values to create a combined loss value. The computing system creates an updated design specification using the combined loss value. The generating, determining, combining, and creating actions are repeated until a fabricable segmented design is generated.

Abstract: A multi-channel photonic demultiplexer includes an input region to receive a multi-channel optical signal including four distinct wavelength channels, four output regions, each adapted to receive a corresponding one of the four distinct wavelength channels demultiplexed from the multi-channel optical signal, and a dispersive region optically disposed between the input region and the four output regions. The dispersive region includes a first material and a second material inhomogeneously interspersed to form a plurality of interfaces that each correspond to a change in refractive index of the dispersive region and collectively structure the dispersive region to optically separate each of the four distinct wavelength channels from the multi-channel optical signal and respectively guide each of the four distinct wavelength channels to the corresponding one of the four output regions.

Abstract: A system, apparatus, and method for optimizing structural parameters of a physical device are described. The method includes receiving an initial description of the physical device describing the structural parameters within a simulated environment. The method further includes performing a simulation of the physical device in response to an excitation source to determine a performance metric of the physical device. The simulation environment includes one or more absorbing boundaries for attenuation of an output of the excitation source during the simulation. The method further includes recording attenuated field values of the simulated environment associated with the attenuation during the simulation. The method further includes determining a loss metric based on a difference between the performance metric and a target performance metric, backpropagating the loss metric using the attenuated field values, and generating a revised description of the physical device by updating the structural parameters to reduce the loss metric.

Abstract: A physical voxel, a volumetric testbed, and method for physically simulating a photonic device are described herein. The volumetric testbed comprises a simulation stage and a controller. The simulation stage includes a three-dimensional array of physical voxels configurable to represent the photonic device operating in response to electromagnetic radiation. The physical voxels includes a field detector to measure a local field response and an impedance adjuster to adjust an impedance to the electromagnetic radiation. The controller is coupled to memory, which stores instructions that when executed by one or more processors included in the controller causes the volumetric testbed to perform operations including determining a global field response of the photonic device and adjusting the impedance of the physical voxels to refine a design of the photonic device.

Abstract: Systems and methods described herein may relate to wireless energy transfer between a transmitter and a receiver via resonant coupling. In example embodiments, a method includes identifying a receiver in a wireless power transmission system and identifying a transmitter in the wireless power transmission system. The method also includes determining a real-time per-unit offer corresponding to the identified receiver and determining a real-time per-unit request corresponding to the identified transmitter. The method yet further includes determining a real-time per-unit match based on the offer and the request. The method further includes, in response to determining the match, causing the transmitter to provide electrical energy to the receiver via a wireless resonant coupling link.

Abstract: Disclosed herein is a method of determining an operational configuration of a wireless power adapter. The method includes determining whether the wireless power adapter is calibrated to supply a legacy device with electrical energy. The method further includes, in response to determining that the wireless power adapter is not calibrated to supply the legacy device with electrical energy, delivering a first power signal to the legacy device via a first electrical coupling member. The method also includes detecting a response of the legacy device to receiving the first power signal, and based on the response of the legacy device, determining an operational configuration of the wireless power adapter. Furthermore, the method includes configuring the wireless power adapter to operate according to the determined operational configuration.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving brain activity data of a user from a brainwave sensor and user physiological data from a non-brainwave sensor, where the brain activity data represents a brainwave pattern related to a physiological activity of the user and a brainwave pattern related to a mental activity of the user. Identifying a physiological action of the user based on the user physiological data. Identifying, within the brain activity data, a pattern that is representative of the identified physiological action. Filtering the brain activity data to lessen a contribution of the pattern representative of the identified physiological action to the brain activity data, thereby, providing filtered brain activity data.

Abstract: The present disclosure relates to systems, devices, and methods for calibrating a light field projection system. One example system includes a projection unit operable to project a scanning sequence toward a screen having convex reflective elements. The scanning sequence is modulated according to a baseline intensity profile. The system also includes a calibration device disposed such that a portion of the scanning sequence is intercepted by the calibration device. The calibration device includes a first light detector arranged to detect an intercepted intensity profile. The calibration device also includes a second light detector arranged to detect a reflected portion of the scanning sequence as a measured intensity profile. The system further includes a control system. The control system is configured to determine an expected intensity profile and to modify operation of the light field projection system based on a comparison of the measured intensity profile to the expected intensity profile.

Abstract: A photonic integrated circuit including an optical modulator, one or more waveguides, and an outcoupler is described. The optical modulator includes a modulation region and a modulation actuator. The modulation region includes an inhomogeneous arrangement of two or more different materials having different refractive indexes to structure the modulation region to manipulate one or more optical properties of an optical carrier wave in response to a modulation bias. The modulation actuator is disposed proximate to the modulation region and adapted to apply the modulation bias to the modulation region to generate a first signal and a second signal. The outcoupler is optically coupled to the one or more waveguides to receive the first signal and the second signal and further adapted to preserve the first signal and the second signal as a combined signal directed out of the photonic integrated circuit.

Abstract: A computer-implemented method for modeling fabrication constraints of a fabrication process is described. The method includes receiving training data including pre-fabrication structures and post-fabrication, training a fabrication constraint model by optimizing parameters of the fabrication constraint model based on the training data to model the fabrication constraints of the fabrication process, receiving an input design corresponding to a physical device, and generating a fabricability metric of the input design via the fabrication constraint model. The fabricability metric is related to a probabilistic certainty that the input design is fabricable by the fabrication process determined by the fabrication constraint model.
