Abstract: Configurations for a modal interference device used for wavelength locking are disclosed. The modal interference device may be an interference device that includes an input waveguide, an interference waveguide, and an output waveguide. A fundamental mode of light may be launched into the input waveguide and the interference waveguide may receive the fundamental mode and generate a higher order mode of light, where the two modes of light may be superimposed while propagating through the interference waveguide. The two modes of light may be received at an output waveguide that collapses the two modes into a single mode and generates an output signal corresponding to the interference between the two modes of light. The output signal may be used to wavelength lock a measured wavelength to a target wavelength. The multiple output waveguides may produce output signals that have dead zones that do not align with one another for any wavelength in the wavelength range of interest.

Abstract: Described here are optical sampling architectures and methods for operation thereof. An optical sampling architecture can be capable of emitting a launch sheet light beam towards a launch region and receiving a detection sheet light beam from a detection region. The launch region can have one dimension that is elongated relative to another dimension. The detection region can also have one dimension elongated relative to another dimension such that the system can selectively accept light having one or more properties (e.g., angle of incidence, beam size, beam shape, etc.). In some examples, the elongated dimension of the detection region can be greater than the elongated dimension of the launch region. In some examples, the system can include an outcoupler array and associated components for creating a launch sheet light beam having light rays with different in-plane launch positions and/or in-plane launch angles.

Abstract: Systems and methods reduce power consumption in embedded machine learning hardware accelerators and enable cost-effective embedded at-the-edge machine-learning and related applications. In various embodiments this may be accomplished by using hardware accelerators that comprise a programmable pre-processing circuit that operates in the same clock domain as the accelerator. In some embodiments, tightly coupled data loading first-in-first-out registers (FIFOs) eliminate clock synchronization issues and reduce unnecessary address writes. In other embodiments, a data transformation may gather source data bits in a manner that allows loading full words of native bus width to reduce the number of writes and, thus, overall power consumption.

Abstract: A carbon capture system includes two carbon capture plates. A first carbon capture plate collects carbon dioxide from a flow of ambient air. A second carbon capture plate releases carbon dioxide upon application of heat from a heat exchanger. The heat is exhaust heat from a data center. The first carbon capture plate and the second carbon capture plate are rotatable between the capture and release positions. The carbon capture system uses the waste heat from a data center to collect and store atmospheric carbon dioxide, thereby reducing the concentration of atmospheric carbon dioxide.

Abstract: A power controller allocates input power to a datacenter between computing power for computing services, backup power, and overhead power for overhead systems. The power controller reallocates the overhead power and/or the backup power to the computing power. This may increase the overall utilization of the datacenter by allowing additional processing power of the servers to be used.

Abstract: Described herein are systems and methods for efficiently processing large amounts of data when performing complex neural network operations, such as convolution and pooling operations. Given cascaded convolutional neural network layers, various embodiments allow for commencing processing of a downstream layer prior to completing processing of a current or previous network layer. In certain embodiments, this is accomplished by utilizing a handshaking mechanism or asynchronous logic to determine an active neural network layer in a neural network and using that active neural layer to process a subset of a set of input data of a first layer prior to processing all of the set of input data.

Abstract: A laser chip including a plurality of stripes is disclosed, where a laser stripe can be grown with an initial optical gain profile, and its optical gain profile can be shifted by using an intermixing process. In this manner, multiple laser stripes can be formed on the same laser chip from the same epitaxial wafer, where at least one laser stripe can have an optical gain profile shifted relative to another laser stripe. For example, each laser stripe can have a shifted optical gain profile relative to its neighboring laser stripe, thereby each laser stripe can emit light with a different range of wavelengths. The laser chip can emit light across a wide range of wavelengths. Examples of the disclosure further includes different regions of a given laser stripe having different intermixing amounts.

The second cryptographic key is associated with a second priority indicator. The first priority indicator is compared with the second priority indicator. Responsive to determining that the second priority indicator supersedes the first priority indicator, the first cryptographic key is disabled.

Abstract: A service engine of a processor-based system determines an estimated amount of taxes due in association with a proposed transaction based on a risk tolerance value specified by a party to the transaction, such as a seller. Multiple classification code queries are generated for classifying an item that is the subject of the proposed transaction, from which a plurality of classification code candidates are determined. Each such classification code candidate is considered in determination of multiple corresponding possible tax-due amounts, and the taxes due for the proposed transaction are determined by the service engine based on a statistical calculation corresponding to the specified risk tolerance value. The service engine provides the estimated tax due amount to one or more parties to the proposed transaction.
