  • Publication number: 20250111116
    Abstract: In some embodiments, a computer-implemented method of creating a design for an optoelectronic device is provided. A computing system determines an initial heater design that includes one or more heater parameters. The computing system determines a temperature gradation by simulating performance of the initial heater design in adjusting an environmental temperature to a nominal temperature. The computing system simulates performance of a nominal optimized design of a dispersive region of the optoelectronic device, given the temperature gradation, to determine a temperature-influenced performance loss value. The computing system determines a heater parameter gradient based on the temperature-influenced performance loss value, and revises the heater parameters based at least in part on the heater parameter gradient to create a revised heater design.

  • Publication number: 20250111122
    Abstract: In some embodiments, a computer-implemented method of creating a design for an optoelectronic detector device is provided. A computing system determines an initial design that includes circuit parameters for at least one photodetector region and for conductors that couple the photodetector region to circuitry. The computing system simulates performance of an optically active region to generate a plurality of field values, and simulates performance of the at least one photodetector region based on the plurality of field values to generate charge values. The computing system simulates performance of at least the conductors based on the charge values to generate a performance loss value, and determines a loss metric based on the performance loss value. The computing system backpropagates the loss metric to determine a circuit parameter gradient, and revises the circuit parameters based at least in part on the circuit parameter gradient to create an updated initial design.

  • Publication number: 20250110358
    Abstract: A polarization beam splitter includes an input port, first and second output ports, and a polarization splitting region coupled between the input port and the first and second output ports. The input port is adapted to receive guided optical signals that are polarization multiplexed, including a transverse electric (TE) optical signal and a transverse magnetic (TM) optical signal. The polarization splitting region includes a pattern of at least two materials having different refractive indexes. The pattern is shaped to demultiplex the TE and TM optical signals by directing a first power majority of the TE optical signal received at the input port to the second output port via asymmetrical power splitting while directing a second power majority of the TM optical signal received at the input port to the first output port via multipath interferometry.

  • Publication number: 20240088696
    Abstract: Aspects of a charging system may involve altering the duty cycle of the shaped charge signal over a period of time to alter an average current supplied to an electrochemical device while maintain the maximum current of the charge signal. For example, the average current of the charge signal used to charge a battery may be adjusted by varying the duty cycle or peak current of the shaped charge signal, and may be based, in some instances, on the state of charge, temperature, and/or impedance of the battery. In some instances, control over the average or total current of the charge signal is constrained by the maximum current that the system can supply, such that altering the duty cycle of the charge signal provides control over an average current of the charge signal without needing to supply additional current sources.

  • Patent number: 11537449
    Abstract: Devices and methods for providing alert notifications. The device includes an input module, a display, and memory having instructions. The device receives, via the input module, a first signal representing a command to set an alert condition associated with an identifier and, in response, generates the alert condition. The device transmits a second signal representing the alert condition to a monitoring system for setting up a targeted notification. The device receives a third signal representing an asserted alert indicating that the alert condition is satisfied and displays on the display, based on the third signal representing the asserted alert, an alert notification including the identifier and a first selectable option associated with a first application interface. In response to receiving, via the input module, a fourth signal representing selection of the first selectable option, the device displays the first application interface and auto-populates a first field based on the identifier.
