摘要： An interferometric measurement system includes ports configured to receive an optical signal from an optical source and an optical signal from a target. A photonic integrated circuit includes a variable delay configured to select between at least two optical paths from the input to an output such that the optical signal from the optical source passes to the output while experiencing an optical delay based on a selected one of the at least two optical paths where a loss of the optical signal from the optical source provided to the input that passes to the output is nominally the same for each of the at least two optical paths. An optical receiver is configured to receive the optical signal from the target and to receive the optical signal from the optical source that experiences the optical delay based on the selected one of the at least two optical paths and generates a corresponding electrical receive signal at an electrical output. A processor is configured to generate an interferometric measurement signal based on the receive signal.

摘要： An optical probe imaging system includes an optical probe having a multicore optical fiber. Distal optics image light propagating in the multicore optical fiber so as to generate a light pattern on a sample that is based on a relative position of the cores. A distal motor causes the light pattern to traverse a path across the sample. An optical receiver includes a first receiver receiving light that has traversed the path across the sample from one of the at least two cores and a second receiver receiving light that has traversed the path across the sample from the other of the cores, such that the first receiver and the second receiver detect light in parallel. A processor maps relative position of the cores at the distal facet based on signals generated by the receiver.

摘要： An optical-fiber measurement system includes an optical transceiver comprising an optical transmitter and an optical receiver. A multi-core optical fiber has a proximal end with a first optical core coupled to the transceiver and a second optical core coupled to the transceiver, and a distal end with the first optical core coupled to a sample path that is configured to convey light collected from a sample positioned external to the multi-core optical fiber and the second optical core coupled to a reference path such that the sample path and the reference path experience mostly a same disturbance along the multi-core optical fiber. The optical receiver is configured to interferometrically detect light from the sample path and light from the reference path.

摘要： A wavelength tunable laser device includes a gain element positioned in an optical cavity that provides optical gain to an optical signal. A frequency shifter that generates a frequency shift as a function of time is positioned in the optical cavity. The optical cavity is configured so that a magnitude of the frequency shift as a function of time generated by the frequency shifter is substantially equal to a frequency separation of a cavity mode of the cavity such that an output of the cavity generates laser light having a wavelength that tunes as a function of time.

摘要： An optical system for producing an optical probe beam includes an optical source that generates a free-space optical beam. An optical element is positioned in a path of the free-space optical beam to project the free-space optical beam to generate a projected free-space optical beam.

摘要： Disclosed herein are optical integration technologies, designs, systems and methods directed toward Optical Coherence Tomography (OCT) and other interferometric optical sensor, ranging, and imaging systems wherein such systems, methods and structures employ tunable optical sources, coherent detection and other structures on a single or multichip monolithic integration. In contrast to contemporary, prior-art OCT systems and structures that employ simple, miniature optical bench technology using small optical components positioned on a substrate, systems and methods according to the present disclosure employ one or more photonic integrated circuits (PICs), use swept-source techniques, and employ a widely tunable optical source(s).In another embodiment the system uses an optical photonic phased array. The phase array can be a static phased array to eliminate or augment the lens that couples light to and from a sample of interest or can be static and use a spectrally dispersive antenna and a tunable source to perform angular sweeping. The phased array can be active in 1 or 2 dimensions so as to scan the light beam in angle. The phased array can also adjust focus. The phased array can implement an optical waveform that will extend depth of field focus for imaging. The phase array can also be a separate standalone element that is fed by one or more optical fibers. The phased array can be for scanning a biomedical specimen used in conjunction with a swept-source OCT system, can be used in a free-space coherent optical communication system for beam pointing or tracking, used in LIDAR applications, or many other beam control or beam steering applications.

摘要： Exterior building siding for aesthetic and protection of the building against wind, rain and solar energy that includes attaching each horizontal plank from the top of the wall downwardly that includes a starting strip where each plank is interlocked to the plank above it. Each of the horizontal planks includes a top wall portion that fits snuggly into an “L-shaped” groove above it so that the panels can be firmly locked together vertically in a downwardly fashion to prevent any wind uplift against the siding or moisture intrusion.
