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 computer-implemented method for revising structural parameters of a physical device is provided. The method comprises configuring a simulated environment to be representative of the physical device based on an initial description that describes structural parameters of the physical device. The method further includes performing an operational simulation of the physical device based on training data representative of physical stimuli within a physical domain to simulate an interaction between the physical device and the physical stimuli. The method further includes computing a loss value based on a simulated output of the physical device and performing and adjoint simulation by backpropagating the loss value through the simulated environment. The method also includes generating a revised description of the physical device by updating the structural parameters to reduce the loss value.

Abstract: An example method may include receiving, from a client computing device, an indication of a target drop-off spot for an object within a first virtual model of a first region of a delivery destination. A second virtual model of a second region of the delivery destination may be determined based on sensor data received from one or more sensors on a delivery vehicle. A mapping may be determined between physical features represented in the first virtual model and physical features represented in the second virtual model to determine an overlapping region between the first and second virtual models. A position of the target drop-off spot within the second virtual model may be determined based on the overlapping region. Based on the position of the target drop-off spot within the second virtual model, the delivery vehicle may be navigated to the target drop-off spot to drop off the object.

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 multilayer photonic device is described, including an input region configured to receive an input signal, a multilayer stack optically coupled with the input region to receive the input signal, and an output region optically coupled with the multilayer stack to output an output signal. The multilayer stack can include a first metastructured dispersive region disposed in a first patterned layer of the multilayer stack and a second metastructured dispersive region disposed in a second patterned layer of the multilayer stack and optically coupled with the first metastructured dispersive region. The first metastructured dispersive region and the second metastructured dispersive region can together structure the multilayer stack to generate the output signal in response to the input signal.

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: Examples implementations relate to navigation path determination. An example method includes receiving, at a computing system, video data showing a demonstration path for navigating a location. The method further includes identifying, using the video data, a set of permissible surfaces at the location, wherein each permissible surface was traversed by the demonstration path. The method additionally includes determining a navigation path for a vehicle to follow at the location, wherein the navigation path includes a variation from the demonstration path such that the variation causes the vehicle to stay within one or more permissible surfaces from the set of permissible surfaces. The method also includes causing, by the computing system, the vehicle to follow the navigation path to navigate the location.
