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: Methods and systems for measuring one or more properties of a sample are disclosed. The methods and systems can include multiplexing measurements of signals associated with a plurality of wavelengths without adding any signal independent noise and without increasing the total measurement time. One or more levels of encoding, where, in some examples, a level of encoding can be nested within one or more other levels of encoding. Multiplexing can include wavelength, position, and detector state multiplexing. In some examples, SNR can be enhanced by grouping together one or more signals based on one or more properties including, but not limited to, signal intensity, drift properties, optical power detected, wavelength, location within one or more components, material properties of the light sources, and electrical power. In some examples, the system can be configured for optimizing the conditions of each group individually based on the properties of a given group.

Abstract: Various embodiments disclosed herein describe photonic switch. The controllable photonic switch may be configured with an asymmetry and different doping level that concurrently route two different wavelengths of light by wavelength-dependent phase shifters. In some instances, the controllable photonic switch includes a waveguide having an asymmetric cross-sectional shape. In other instances, the controllable photonic switch selectively route different wavelengths of light to different outputs of the controllable photonic switch.

Abstract: Configurations for light source modules and methods for mitigating coherent noise are disclosed. The light source modules may include multiple light source sets, each of which may include multiple light sources. The light emitted by the light sources may be different wavelengths or the same wavelength depending on whether the light source module is providing redundancy of light sources, increased power, coherent noise mitigation, and/or detector mitigation. In some examples, the light source may emit light to a coupler or a multiplexer, which may then be transmitted to one or more multiplexers. In some examples, the light source modules provide one light output and in other examples, the light source modules provide two light outputs. The light source modules may provide light with approximately zero loss and the wavelengths of light may be close enough to spectroscopically equivalent respect to a sample and far enough apart to provide coherent noise mitigation.

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: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

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, et al. on 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: Methods and systems concerning demultiplexing and multiplexing light in optical multiplexing systems are disclosed herein. An optical multiplexing system may include a number of light emitters and a number of associated waveguides. Light emitted from each of the number of light emitters may travel through the associated waveguide and may enter a multiplexer, where a multiplexing operation may occur. At least one of the number of light emitters may be configured to emit light with multiple wavelengths. Such a light emitter may further be associated with a demultiplexer to demultiplex the light with multiple wavelengths before the light reaches a multiplexer. After a demultiplexing operation, the demultiplexed light may be directed to multiple waveguides and the multiple waveguides may guide the demultiplexed light to a multiplexer.

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.
