Abstract: Configurations for a photonics assembly design and methods for mitigating coherent noise thereof are disclosed. The photonics assembly may include a set of light sources, an optical subsystem that may include a set of optical elements, and a diffusing element. The light emitted by the set of light sources may be different wavelengths and the light may be de-cohered by a phase shifter before being received by the set of optical elements. The diffusing element may be moveable and may be capable of repeating the same positions or set of positions for each beam of light emitted by the set of light sources. By combining the coherent noise mitigation techniques of the moveable diffusing element and the de-cohered light, the photonics system may provide an illumination profile with a specific spatial profile and angular profile on the sample that allows reliable measurement of the sample and coherent noise mitigation.

Abstract: Embodiments are directed to optical measurement systems that utilize multiple emitters to emit light during a measurement, as well as methods of performing measurements using these optical measurement systems. The optical measurement systems may include a light generation assembly that is configured to generate light via a light source unit, and a photonic integrated circuit that includes a launch group having a plurality of emitters. Each of these emitters is optically coupled to the light generation assembly to receive light generated from the light generation assembly, and may emit this light from a surface of the photonic integrated circuit. The optical measurement system may perform a measurement in which the light generation assembly generates light and each of the plurality of emitters simultaneously emit light received from the light generation assembly.

Abstract: Disclosed herein is an integrated photonics device including an on-chip wavelength stability monitor. The wavelength stability monitor may include one or more interferometric components, such as Mach-Zehnder interferometers and can be configured to select among the output signals from the interferometric components for monitoring the wavelength emitted by a corresponding photonic component, such as a light source. The selection may be based on a slope of the output signal and in some examples may correspond to a working zone at or around a wavelength or wavelength range. In some examples, the interferometric components can be configured with different phase differences such that the corresponding working zones have different wavelengths. In some examples, the slopes of the output signals may be weighted based on the steepness of the slope and all of the output signals may include information for wavelength locking the measured wavelength to the target wavelength.

Abstract: Methods, systems, and devices are described for managing network communications.

Abstract: Methods, systems, and devices are described for managing network communications. A traffic manager module configured to serve as a proxy between a plurality of client devices and a network service may receive a plurality of messages for the network service. Each message may be associated with at least one QoS parameter. The traffic manager module may transmit the plurality of messages to the network service over a connection between the traffic manager module and the network service.

Abstract: Methods, systems, and devices are described for managing network communications. A traffic manager module may receive a message from a first network device to a second network device. The traffic manager module may serve as a proxy between the first network device and the second network device. The traffic manager module may perform an application layer inspection at the traffic manager module on at least one of the message or a response to the message from the second network device, and forward the message or the response to the message to a third network device based on the application layer inspection at the traffic manager module.

Abstract: Methods, systems, and devices are described for stateful failover in traffic manager module functioning as a proxy between at least one first network device and at least one server. In a first set of embodiments, an amount of synchronized state information may be reduced through a controlled use of acknowledgment messages. In a second set of embodiments, state information may be synchronized to a standby traffic manager module in response to changes in a sequence number delta between two logically paired connections. In a third set of embodiments, connections may be restored at a standby traffic manager module based on stored connection information, a synchronized sequence number delta stack, and rediscovered sequence numbers.

Abstract: Methods, systems, and devices are described for managing network communications at a traffic manager module serving as a proxy to at least one network service for at least one client device. The traffic manager module may maintaining a SYN request cache for a socket implemented by the traffic manager module. Active SYN request messages may be stored at the socket in the SYN request cache. The traffic manager module may determine a status of the SYN request cache and ignore additional SYN request messages at the socket based on the determined status of the SYN request cache.
