Abstract: Systems and methods for determining one or more properties of a sample are disclosed. The systems and methods disclosed can be capable of measuring along multiple locations and can reimage and resolve multiple optical paths within the sample. The system can be configured with one-layer or two-layers of optics suitable for a compact system. The optics can be simplified to reduce the number and complexity of the coated optical surfaces, etalon effects, manufacturing tolerance stack-up problems, and interference-based spectroscopic errors. The size, number, and placement of the optics can enable multiple simultaneous or non-simultaneous measurements at various locations across and within the sample. Moreover, the systems can be configured with an optical spacer window located between the sample and the optics, and methods to account for changes in optical paths due to inclusion of the optical spacer window are disclosed.

Abstract: An illuminator/collector assembly can deliver incident light to a sample and collect return light returning from the sample. A sensor can measure ray intensities as a function of ray position and ray angle for the collected return light. A ray selector can select a first subset of rays from the collected return light at the sensor that meet a first selection criterion. In some examples, the ray selector can aggregate ray intensities into bins, each bin corresponding to rays in the collected return light that traverse within the sample an estimated optical path length within a respective range of optical path lengths. A characterizer can determine a physical property of the sample, such as absorptivity, based on the ray intensities, ray positions, and ray angles for the first subset of rays. Accounting for variations in optical path length traversed within the sample can improve accuracy.

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: 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: 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 launchregion 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.
