[0011] Disclosed herein are apparatus, systems, and methods related to intelligent photonic device health management. As discussed above, one problem that arises in the use of the device is determining the health of the photonic components. The performance of the device may degrade as the photonic components age, thereby deteriorating the health of the photonic components. This is due, for example, to drift, as the operational values ​​assumed to be being used by the photonic components drift away from their target values, thereby making the performance of the photonic components less accurate. Another reason for deteriorating the health of the photonic device is a reduction in the device's ability to generate signal strength.

[0012] By understanding the aging performance characteristics of a photonic component, its performance can be optimized until the device or component is eventually replaced. One way to achieve this is by using a computing device that can receive device design parameters, operating parameters, and / or throughput characteristics (also referred to herein as device throughput characteristics) corresponding to a photonic component (e.g., a photonic accelerator component) within a device.

[0013] One type of device that uses photonic components is an intelligent Power over Ethernet (PoE) device. Such devices may contain photonic accelerator components, photonic on-chip components, and / or off-chip communications. For example, in some devices, photonic accelerators are used to perform video analytics or other computer vision related tasks.

[0014] To detect aging-related characteristics of photonic components, Smart PoE includes a photon detection system / module. The components that make up the system can be placed on the same chip as the photonic components (e.g., photonic accelerators) or as separate modules.

[0015] The waveguides carrying photon signals within these photon components may have branches generated via splitters in the main waveguide. In such embodiments, the branched portion of the photon signal split from the main waveguide that the photon components and NVR components use to communicate, for example, will pass through the branch waveguide, and this branch photon signal can be read using a photodetector.

[0016] From this branch photon signal, characteristics of aging can be sensed and identified. For example, a drop in signal output and / or a drift from a selected resonant wavelength are characteristics of aging, and both will be reflected in a reduction in power output from the photodetector. The power output can be expressed as the total signal density of the main waveguide photon signal.

[0017] The power output may be quantified by measuring (sensing) by a photodiode in a photodetector. The photodiode converts the photon signal into a current, and the current value may then be compared to a threshold current value by a current threshold detector. For example, if the sensed power output (the current produced by the photodiode and compared by the current threshold detector) drops below a threshold, then it may be determined that corrective measures to tune the photonic assembly may be required, such as compensating for the drop in power output by adding a photon signal boost equivalent to a drop in the sensed current.

[0018] To identify this problem with a photonic component, once the current threshold detector detects that the photonic signal fails to generate a threshold current, a spike signal may be generated from the current threshold detector, which in turn may drive a vertical cavity surface emitting laser (VCSEL) to generate a laser pulse, which is sent to a central control system of the photonic device or component. The VCSEL of each module / component / device may have a specific wavelength assigned to it, so that the laser detection component of the central control system may immediately identify a module / component / device with an aging problem.

[0019] Examples of embodiments of the present disclosure may, for example, include a photon detection system. This system may include: a communication bus for transmitting a main photon waveguide signal therethrough; a splitter that splits a portion of the main photon waveguide signal to generate a branched partial photon signal; a photodetector that converts the branched partial photon signal into a converted current; a current threshold detector that compares the converted current with a threshold. This comparison determines whether the converted current exceeds the threshold. If the converted current does not exceed the threshold, the current threshold detector generates a laser generation signal directed to the VCSEL. The laser generation signal drives the VCSEL to generate a laser signal directed to a central control system.

[0020] A single photon health management platform may include one or more reconfigurable photon detection systems, such as Figure 2 In such embodiments, these probes may be reconfigurable in the sense that light from multiple photonic devices may be selectively routed to a single probe using a photon splitter. Additionally, the waveguides in such a system may carry one or more wavelengths, and thus, in some embodiments, the photon detection system may selectively filter and evaluate one or more of these wavelengths.

[0021] In some embodiments, the photon detection system may be configured to route wavelengths to one or more probes. Embodiments may also include the ability to tune the VCSEL using electrical components after deployment. This allows the VCSEL to send a unique laser signal when evaluating different wavelength signals. For example, a splitter may be configured to split a portion of a first wavelength, and the laser signal provides a unique signal representing the first wavelength known to the central control system. Then, the splitter may be reconfigured to split a portion of a second wavelength, and the laser signal provides a unique signal representing the second wavelength known to the central control system.

[0022] The photonic device may be an edge device. An edge device describes an electronic device that has processing capabilities and connects and / or exchanges data with other devices and systems through a communication network. For example, an edge device may include an Internet of Things (IoT) device and / or a user equipment (UE). A UE may include a handheld device such as a handheld phone and / or a laptop equipped with a mobile broadband adapter, among other possible devices.

[0023] IoT devices may include devices that include sensors and can exchange data collected from the sensors. IoT devices may include smart home devices such as thermostats and doorbells and / or wearable devices such as smart watches, among other possible IoT devices. Edge devices may be end nodes, such as cameras. Edge devices may also include, for example, drones with one or more cameras (imaging components). In many examples, a photonic device (e.g., an edge device) including a photonic accelerator may be a PoE device, where the device receives its power via an Ethernet connection.

[0024] As used herein, a photon accelerator is hardware that accelerates a specific class of computations in the optical domain to address the growing demand for computing resources and capacity. A photon accelerator can be used to perform matrix multiplication using planar light conversion methods, Mach-Zehnder interferometer methods, and / or wavelength division multiplexing methods, among other methods. For example, a photon accelerator can be used to process images captured by a camera. Typically, a photon component such as a photon accelerator can be a processing device.

[0025] Figure 1 An example monitoring system at a facility utilizing devices having photonic components according to some embodiments of the present disclosure is illustrated. Monitoring system 100 includes several cameras 103. Cameras 103 are each photonic devices in that they include photonic components, such as photonic accelerators.

[0026] The camera 103 may be coupled to a network video recorder (NVR) 104, which is a computing device that records data from the camera 103. The camera 103 may be powered using one or more PoE components. These PoE camera devices 103 may be coupled to the NVR device 104, such that the camera device 103 is coupled to the NVR device 104 through the PoE component. The PoE component may provide power to the device 103, and may route signals provided by the camera device 103 to the NVR device. The NVR device may store the signals provided by the camera device 103 to record data (e.g., video data) provided by the camera device 103.

[0027] Given that the PoE components and / or NVR devices may be used to collect device operating parameters of the devices 103, the PoE components and / or NVR devices may be referred to herein as smart devices / components. For example, the PoE components and / or NVR devices may request device operating parameters from each device 103. Upon receiving the device operating parameters from the devices 103, the PoE components and / or NVR devices may provide the device operating parameters to a health monitoring computing device connected to or as part of the system 100. The PoE components and / or NVR devices may collect the device operating parameters for use in determining device characteristics that may be adjusted based on the health of the photonic components.

[0028] In addition to receiving the device operating parameters, the health monitoring computing device may also access device design parameters for each device 103. The health monitoring computing device may have previously stored the device design parameters in a memory subsystem of the health monitoring computing device.

[0029] To improve the performance or extend the life of a photonic device or component, photon aging data can be used, for example, to derive a loss gradient. The loss gradient represents the error between an estimated photon value (e.g., a photonic device / component throughput prediction) and a true photon value (e.g., a photonic device / component throughput characteristic). The loss gradient can be used to add or adjust a weight value (an enhancement signal that can be applied to a photon signal to improve the photonic device / component throughput) that can be applied to a system to account for photonic device / component aging to improve the performance of the photonic device / component.

[0030] In various examples, the processing resources of system 100 can perform back propagation using the loss gradient calculated using the loss function to add or update the weights applied to the system. The processing resources of system 100 can generate the loss function to generate the loss gradient. In various examples, the loss function and back propagation can be performed by different devices.

[0031] The device 103 may include hardware, firmware, and / or software configured to perform operations utilizing a photon accelerator. The health monitoring computing device and the device 103 may further include a memory subsystem (e.g., a non-transitory MRM) on which instructions (e.g., instructions) and / or data (e.g., configurations) may be stored.

[0032] Device 103 may include a photon accelerator. Device 103 may perform measurements to generate device operating parameters. Edge device 103 including a processor may cause device operating parameters to be generated.

[0033] Figure 2 2 is a functional block diagram of a photon detection system for monitoring the health of a device having a photonic component within a system according to some embodiments of the present disclosure. The system 210 includes a communication bus 215 for transmitting an optical signal 211 thereon, and has a waveguide splitter 220 to split a portion 213 of the signal 211 that can be used to analyze the health of the photonic component. Figure 2 In an embodiment of the present invention, the system 210 receives a main waveguide photon signal 211 and splits a branch portion 213 of the signal 211 using a splitter 220. This branch portion 213 can then be analyzed using several elements, such as a directional coupler 218 for directing the branch portion to other elements, a photodetector 216 for converting the photon signal 213 into a current, and a current threshold detector 214 for determining whether the converted current of the signal 213 is below a threshold. If the current is below the threshold, the current threshold detector also generates a spike signal. The spike signal is sent to the VCSEL 212, which generates a laser pulse 219 that is sent to a central control system. In some embodiments, the system 210 also includes a receiver 217 for collecting the remaining portion of the branch signal.

[0034] The VCSEL may generate laser pulses 219 at a unique wavelength that identify to the central control system the photonic component / device to which the photon detection system 210 is connected. For example, if the photon detection system determines that the power output has dropped below a threshold, a current spike may be generated by the current threshold detector 214 and sent to the VCSEL 212. The current spike provides power to drive the VCSEL 212 to generate a laser signal.

[0035] This unique signal is sent to the central control system (such as Figure 3 The central control system shown) can make the necessary signal adjustments. By using this unique identification process, the central control system can make adjustments to the correct photonic device / component.

[0036] In some embodiments, the photodetector will detect the energy envelope at different wavelengths in the communication bus. Whenever it detects these multiple wavelengths passing through the detector, it will generate a certain amount of current based on the expected wavelength being analyzed. If the current is below a threshold, a spike signal is generated, which is used to drive the VCSEL to produce its laser signal, which will alert the central control system to a problem with the photonic component identified by that specific wavelength.

[0037] The splitter may be designed to split a small portion (eg, 5%) of the main signal. In such embodiments, this small loss of signal strength will not adversely affect the communication of information on the main waveguide photonic signal.

[0038] Figure 3 is a block diagram of an example computer system in which embodiments of the present disclosure may operate. For example, Figure 3 An example machine is illustrated of a computer system 390 within which a set of instructions for causing the machine to perform any one or more of the methodologies discussed herein may be executed. This computer system may serve as the central control system described above.

[0039] In some embodiments, computer system 390 may correspond to a host system that includes, is coupled to, or utilizes a memory subsystem (e.g., a memory subsystem).

[0041] The example computer system 390 includes a processing device (e.g., a processor) 391, a main memory 393 (e.g., read-only memory (ROM), flash memory, dynamic random access memory (DRAM), such as synchronous DRAM (SDRAM) or Rambus DRAM (RDRAM)), etc.), a static memory 397 (e.g., flash memory, static random access memory (SRAM)), etc.) and a data storage system 398, which communicate with each other via a bus 396.

[0042] The processing device 391 represents one or more general-purpose processing devices, such as a microprocessor, a central processing unit, or the like. More specifically, the processing device 391 may be a complex instruction set computing (CISC) microprocessor, a reduced instruction set computing (RISC) microprocessor, a very long instruction word (VLIW) microprocessor, or a processor implementing other instruction sets or multiple processors implementing a combination of instruction sets.

For example, processing device 391 may operate a laser sensing component to sense when a signal from a VCSEL has been received and determine which photonic device / component has a problem based on the unique identifier signal sent.

[0045] Although the machine-readable storage medium 399 is shown as a single medium in the example embodiment, the term "machine-readable storage medium" should be considered to include a single medium or multiple media storing one or more sets of instructions. The term "machine-readable storage medium" should also be considered to include any medium capable of storing or encoding a set of instructions for execution by a machine and causing the machine to perform any one or more of the methods of the present disclosure. Thus, the term "machine-readable storage medium" should be considered to include (but not limited to) solid-state memory, optical media, and magnetic media.
